    The war in Afghanistan (or the American war in    Afghanistan)[29][30] is the period in    which the United States invaded Afghanistan after the September 11 attacks.[31] Supported initially by close    allies, they were later joined by NATO beginning in 2003. It followed the Afghan Civil War's    19962001 phase. Its public aims were to dismantle al-Qaeda and to deny it a    safe base of operations in Afghanistan by removing the Taliban from power.[32] Key allies, including the United    Kingdom, supported the U.S. from the start to the end of the    phase. This phase of the War is the longest    war in United States history.[33][34][35][36][37]  
    In 2001, U.S. President George W. Bush demanded that the Taliban    hand over Osama bin Laden and expel al-Qaeda; bin    Laden had already been wanted by the United Nations since 1999.    The Taliban declined to extradite him unless given    what they deemed convincing evidence of his involvement in the    9/11 attacks[38] and declined    demands to extradite other terrorism suspects apart from bin    Laden. The request was dismissed by the U.S. as a delaying    tactic, and on 7 October 2001 it launched Operation Enduring Freedom    with the United Kingdom. The two were later joined    by other forces, including the Northern    Alliance.[39][40] In    December 2001, the United Nations Security    Council established the International    Security Assistance Force (ISAF), to assist the Afghan    interim authorities with securing Kabul. At the Bonn    Conference in December 2001, Hamid Karzai was selected to head the    Afghan Interim    Administration, which after a 2002 loya    jirga in Kabul    became the Afghan Transitional    Administration. In the popular elections of    2004, Karzai was elected president of the country, now    named the Islamic Republic of    Afghanistan.[41]  
    NATO became involved as an alliance in August 2003, taking the    helm of the International    Security Assistance Force (ISAF), and later that year    assumed leadership of ISAF with troops from 43 countries. NATO    members provided the core of the force.[42] One portion of U.S. forces    in Afghanistan operated under NATO command; the rest remained    under direct U.S. command. Taliban leader Mullah Omar    reorganized the movement, and in 2003, launched an    insurgency against the government and ISAF.[43][44] Though outgunned and    outnumbered, insurgents from the Taliban, Haqqani Network, Hezb-e-Islami Gulbuddin and other    groups have waged asymmetric warfare with guerilla raids and ambushes in the countryside, suicide attacks against urban targets and    turncoat killings    against coalition forces. The Taliban exploited weaknesses in    the Afghan government, among the most corrupt in the    world, to reassert influence across rural areas of southern    and eastern Afghanistan. ISAF responded in 2006 by increasing    troops for counterinsurgency    operations to "clear and hold" villages and "nation building" projects to    "win hearts and minds".[45][46] While ISAF    continued to battle the Taliban insurgency, fighting crossed    into neighboring North-West    Pakistan.[47]  
    On 2 May 2011, United States Navy SEALs    killed Osama bin Laden in    Abbotabad, Pakistan. In May 2012, NATO leaders    endorsed     an exit strategy for withdrawing their forces. UN-backed    peace talks have since taken place between the Afghan    government and the Taliban.[48] In May 2014,    the United States announced that "[its] combat operations    [would] end in 2014, [leaving] just a small residual force in    the country until the end of 2016".[49] As of 2015, tens of    thousands of people have been killed in the war. Over 4,000    ISAF soldiers and civilian contractors as well as over 15,000    Afghan national security forces members have been killed, as    well as nearly 20 thousand civilians. In October 2014, British    forces handed over the last bases in Helmand to the Afghan    military, officially ending their combat operations in the    war.[50] On 28 December 2014, NATO    formally ended combat operations in Afghanistan and transferred    full security responsibility to the Afghan government, via a    ceremony in Kabul.[51][52]  
    Afghanistan's political order began to break down with the    overthrow of King Zahir Shah by    his cousin Mohammed Daoud Khan in a bloodless    1973 coup. Daoud Khan had served as prime minister since    1953 and promoted economic modernization, emancipation of    women, and Pashtun nationalism. This was threatening to    neighboring Pakistan, faced with its own restive Pashtun population. In    the mid-1970s, Pakistani Prime Minister Zulfikar Ali Bhutto began to    encourage Afghan Islamic leaders such as Burhanuddin Rabbani and Gulbuddin Hekmatyar, to fight against    the regime. In 1978, Daoud Khan was killed in a coup by    Afghan's Communist Party, his former partner in government,    known as the People's Democratic    Party of Afghanistan (PDPA). PDPA pushed for a socialist    transformation by abolishing arranged marriages, promoting mass    literacy and reforming land ownership. This undermined the    traditional tribal order and provoked opposition from Islamic    leaders across rural areas. The PDPA's crackdown was met with    open rebellion, including Ismail Khan's Herat Uprising. The PDPA was beset by    internal leadership differences and was weakened by an internal    coup on 11 September 1979 when Hafizullah Amin ousted Nur    Muhammad Taraki. The Soviet Union, sensing PDPA weakness,    intervened militarily three    months later, to depose Amin and install another PDA faction led by    Babrak    Karmal.  
    The entry of the Soviet Union into Afghanistan in December 1979    prompted its Cold    War rivals, the United States, Pakistan, Saudi Arabia and    China to support rebels    fighting against the Soviet-backed Democratic Republic of    Afghanistan. In contrast to the secular and socialist    government, which controlled the cities, religiously motivated    mujahideen    held sway in much of the countryside. Beside Rabbani,    Hekmatyar, and Khan, other mujahideen commanders included    Jalaluddin Haqqani. The CIA worked    closely with Pakistan's Inter-Service Intelligence to    funnel foreign support for the mujahideen. The war also    attracted Arab volunteers, known as "Afghan Arabs",    including Osama bin Laden.  
    After the withdrawal of the    Soviet military from Afghanistan in May 1989, the PDPA    regime under Najibullah held on until 1992, when    the collapse of the Soviet Union deprived the regime of aid,    and the defection of Uzbek general Abdul    Rashid Dostum cleared the approach to Kabul. With the political stage cleared of    Afghan socialists, the remaining Islamic warlords vied for    power. By then, Bin Laden had left the country. The United    States' interest in Afghanistan also diminished.  
    In 1992, Rabbani officially became president of the Islamic State of    Afghanistan, but had to battle other warlords for control    of Kabul. In late 1994, Rabbani's defense minister, Ahmad    Shah Massoud defeated Hekmatyr in Kabul and ended ongoing    bombardment of the capital.[53][54][55]    Massoud tried to initiate a nationwide political process with the goal of    national consolidation. Other warlords,    including Ismail Khan in the west and Dostum in the north    maintained their fiefdoms.  
    In 1994, Mohammed Omar, a mujahideen member who    taught at a Pakistani madrassa, returned to    Kandahar and formed the Taliban movement. His followers were    religious students, known as the Talib and they sought    to end warlordism through strict adherence to Islamic law. By November 1994, the Taliban    had captured all of Kandahar Province. They declined the    government's offer to join in a coalition government and    marched on Kabul in 1995.[56]  
    The Taliban's early victories in 1994 were followed by a series    of costly defeats.[57]    Pakistan provided strong support to the Taliban.[58][59]    Analysts such as Amin Saikal described the group as developing    into a proxy    force for Pakistan's regional interests, which the Taliban    denied.[58]    The Taliban started shelling Kabul in early 1995, but were    driven back by Massoud.[54][60]  
    On 27 September 1996, the Taliban, with military support by    Pakistan and financial support from Saudi Arabia,    seized Kabul and founded the Islamic Emirate of    Afghanistan. They imposed their fundamentalist interpretation of    Islam in areas under their control, issuing edicts forbidding    women to work outside the home, attend school, or to leave    their homes unless accompanied by a male relative.[62]    According to the Pakistani expert Ahmed Rashid, "between 1994 and 1999,    an estimated 80,000 to 100,000 Pakistanis trained and fought in    Afghanistan" on the side of the Taliban.[63][64]  
    Massoud and Dostum, former arch-enemies, created a United Front    against the Taliban, commonly known as the Northern    Alliance.[65] In addition to Massoud's    Tajik force and Dostum's Uzbeks, the United Front    included Hazara factions and Pashtun forces under the leadership of    commanders such as Abdul Haq and Haji    Abdul Qadir. Abdul Haq also    gathered a limited number of defecting Pashtun Taliban.[66] Both agreed to    work together with the exiled Afghan king Zahir    Shah.[64]    International officials who met with representatives of the new    alliance, which the journalist Steve Coll referred to as the "grand    Pashtun-Tajik alliance", said, "It's crazy that you have this    today  Pashtuns, Tajiks, Uzbeks, Hazara  They were all ready    to buy in to the process  to work under the king's banner for    an ethnically balanced Afghanistan."[68] The Northern    Alliance received varying degrees of support from Russia, Iran,    Tajikistan and India.  
    The Taliban captured Mazar-i-Sharif in 1998 and drove Dostum    into exile.  
    The conflict was brutal. According to the United    Nations (UN), the Taliban, while trying to consolidate    control over northern and western Afghanistan, committed    systematic massacres against civilians. UN officials stated    that there had been "15 massacres" between 1996 and 2001. The    Taliban especially targeted the Shiite Hazaras.[69][70] In    retaliation for the execution of 3,000 Taliban prisoners by    Uzbek general Abdul Malik Pahlawan in 1997, the    Taliban executed about 4,000 civilians after taking    Mazar-i-Sharif in 1998.[71][72]  
    Bin Laden's so-called 055 Brigade was responsible for mass-killings    of Afghan civilians.[73] The    report by the United Nations quotes eyewitnesses in many    villages describing "Arab fighters carrying long knives used    for slitting throats and skinning people".[69][70]  
    By 2001, the Taliban controlled as much as 90% of the country,    with the Northern Alliance confined to the country's northeast    corner. Fighting alongside Taliban forces were some    28,00030,000 Pakistanis and 2,0003,000 Al-Qaeda    militants.[56][73]    Many of the Pakistanis were recruited from madrassas.[73] A    1998 document by the U.S. State    Department confirmed that "2040 percent of [regular]    Taliban soldiers are Pakistani." The document said that many of    the parents of those Pakistani nationals "know nothing    regarding their child's military involvement with the Taliban    until their bodies are brought back to Pakistan". According to    the U.S. State Department report and reports by Human Rights    Watch, other Pakistani nationals fighting in Afghanistan were    regular soldiers, especially from the Frontier    Corps, but also from the army providing direct combat    support.[59][76]  
    In August 1996, Bin Laden was forced to leave Sudan and arrived    in Jalabad, Afghanistan. He had founded Al-Qaeda in the late    1980s to support the mujahideen's war against the Soviets, but    became disillusioned by infighting among warlords. He grew    close to Mullah Omar and moved Al-Qaeda's operations to eastern    Afghanistan.  
    The 9/11 Commission in the U.S. reported    found that under the Taliban, al-Qaeda was able to use    Afghanistan as a place to train and indoctrinate fighters,    import weapons, coordinate with other jihadists, and plot    terrorist actions. While al-Qaeda maintained    its own camps in Afghanistan, it also    supported training camps of other organizations. An estimated    10,000 and 20,000 men passed through these facilities before    9/11, most of whom were sent to fight for the Taliban against    the United Front. A smaller number were inducted into al-Qaeda.  
    After the August 1998    U.S. Embassy bombings were linked to bin Laden, President    Bill    Clinton ordered     missile strikes on militant training camps in Afghanistan.    U.S. officials pressed the Taliban to surrender bin Laden. In    1999, the international community imposed sanctions on the    Taliban, calling for bin Laden to be surrendered. The Taliban    repeatedly rebuffed these demands.  
    Central Intelligence Agency    (CIA) Special Activities Division    paramilitary teams were active in    Afghanistan in the 1990s in clandestine operations to locate    and kill or capture Osama bin Laden. These teams planned    several operations, but did not receive the order to proceed    from President Clinton. Their efforts built relationships with    Afghan leaders that proved essential in the 2001 invasion.  
    During the Clinton    administration, the U.S. tended to favor Pakistan and until    19981999 had no clear policy toward Afghanistan. In 1997, for    example, the U.S. State Department's Robin Raphel told    Massoud to surrender to the Taliban. Massoud responded that, as    long as he controlled an area the size of his hat, he would    continue to defend it from the Taliban.[56]    Around the same time, top foreign policy officials in the    Clinton administration flew to northern Afghanistan to try to    persuade the United Front not to take advantage of a chance to    make crucial gains against the Taliban. They insisted it was    the time for a cease-fire and an arms embargo. At the time, Pakistan    began a "Berlin-like airlift to resupply and re-equip the    Taliban", financed with Saudi money.[80]  
    U.S. policy toward Afghanistan changed after the 1998 U.S. embassy bombings.    Subsequently, Osama bin Laden was indicted for his involvement in the    embassy bombings. In 1999 both the U.S. and the United Nations    enacted sanctions against the Taliban via United    Nations Security Council Resolution 1267, which demanded    the Taliban surrender Osama bin Laden for trial in the U.S. and    close all terrorist bases in Afghanistan.[81] The only collaboration between    Massoud and the US at the time was an effort with the CIA to    trace bin Laden following the 1998 bombings. The U.S. and the    European Union provided no support to Massoud for the fight    against the Taliban.  
    By 2001 the change of policy sought by CIA officers who knew    Massoud was underway. CIA lawyers, working with officers in the    Near East Division and Counter-terrorist Center, began to draft    a formal finding for President George W. Bush's signature,    authorizing a covert action program in Afghanistan. It    would be the first in a decade to seek to influence the course    of the Afghan war in favor of Massoud.Richard A.    Clarke, chair of the Counter-Terrorism Security Group under    the Clinton administration, and later an official in the Bush    administration, allegedly presented a plan to incoming Bush    National    Security Adviser Condoleezza Rice in January 2001.  
    A change in US policy was effected in August 2001. The Bush    administration agreed on a plan to start supporting Massoud. A    meeting of top national security officials agreed that the    Taliban would be presented with an ultimatum to hand over bin    Laden and other al-Qaeda operatives. If the Taliban refused,    the US would provide covert military aid to anti-Taliban groups.    If both those options failed, "the deputies agreed that the    United States would seek to overthrow the Taliban regime    through more direct action."[84]  
    Ahmad Shah Massoud was the only leader of the United Front in    Afghanistan. In the areas under his control, Massoud set up    democratic institutions and signed the Women's Rights Declaration.[85] As a consequence,    many civilians had fled to areas under his control.[86][87] In total, estimates range up to    one million people fleeing the Taliban.[88]  
    In late 2000, Ahmad Shah Massoud, a Tajik nationalist and leader    of the Northern Alliance, invited several    other prominent Afghan tribal leaders to a jirga in northern Afghanistan    "to settle political turmoil in Afghanistan".[89] Among those in attendance    were Pashtun    nationalists, Abdul Haq and Hamid    Karzai.[90][91]  
    In early 2001, Massoud and several other Afghan leaders    addressed the European Parliament in Brussels,    asking the international community to    provide humanitarian help. The Afghan envoy asserted that the    Taliban and al-Qaeda had introduced "a very wrong perception of    Islam" and that without the support of Pakistan and Osama bin    Laden, the Taliban would not be able to sustain their military    campaign for another year. Massoud warned that his intelligence    had gathered information about an imminent, large-scale attack    on U.S. soil.[92]  
    On 9 September 2001, two French-speaking Algerians posing as    journalists killed Massoud in a suicide attack in Takhar    Province of Afghanistan. The two perpetrators were later    alleged to be members of al-Qaeda. They were interviewing Massoud before    detonating a bomb hidden in their video camera.[93][94] Both of the    alleged al-Qaeda men were subsequently killed by Massoud's    guards.  
    On the morning of 11 September 2001, a total of 19 Arab men carried out four    coordinated attacks in the United    States. Four commercial passenger jet airliners were    hijacked.[95][96] The hijackers     members of al-Qaeda's Hamburg cell [97]    intentionally crashed two of the airliners into the Twin Towers    of the World Trade Center    in New York    City, killing everyone on board and more than 2000 people    in the buildings. Both buildings collapsed within two hours    from fire damage related to the crashes, destroying nearby    buildings and damaging others. The hijackers crashed a third    airliner into the Pentagon in Arlington, Virginia, just outside    Washington, D.C.. The fourth plane    crashed into a field near Shanksville, in rural Pennsylvania,    after some of its passengers and flight crew attempted to    retake control of the plane, which the hijackers had redirected    toward Washington, D.C., to target the White House, or the    U.S. Capitol. No one aboard the flights    survived. According to the New York State Health Department,    the death toll among responders including firefighters and    police was 836 as of June 2009.[98] Total deaths were    2996, including the 19 hijackers.[98]  
    The United States invasion of Afghanistan occurred after the    September 11 attacks in late    2001,[99] supported by allies including    the United Kingdom.  
    U.S. President George W. Bush demanded that the Taliban    hand over Osama bin Laden and expel al-Qaeda from    Afghanistan. Bin Laden had been wanted by the U.N. since 1999    for the prior attack on the World Trade Center. The Taliban    declined to extradite him unless the United States    provided convincing evidence of his involvement in the 9/11    attacks.[38] They ignored    U.S. demands to shut down terrorist bases and hand over other    terrorist suspects. The request for proof of bin Laden's    involvement was dismissed by the U.S. as a meaningless delaying    tactic.  
    General Tommy    Franks, then-commanding general of Central Command    (CENTCOM), initially proposed immediately after    the 9/11 attacks to President George W. Bush and Secretary of    Defense Donald Rumsfeld that the U.S. invade    Afghanistan using a conventional force of 60,000 troops,    preceded by six months of preparation. Rumsfield and Bush    feared that a conventional invasion of Afghanistan could bog    down as had happened to the Soviets and the British.[100]    Rumsfield rejected Frank's plan, saying "I want men on the    ground now!" Franks returned the next day with a plan utilizing    Special Forces.[101]    On September 26, 2001, fifteen days after the 9/11 attack, the    U.S. covertly inserted members of the CIA's Special Activities Division    led by Gary    Schroen as part of team Jawbreaker into Afghanistan,    forming the Northern Afghanistan Liaison Team.[102][103][104] They    linked up with the Northern Alliance as part of Task Force    Dagger.[105]  
    Two weeks later, Operational Detachment Alpha (ODA) 555 and    595, both 12-man Green Beret teams from 5th Special Forces    Group, plus Air Force combat controllers, were airlifted by    helicopter from the Karshi-Khanabad Air Base    in Uzbekistan[106] more than 300    kilometers (190mi) across the 16,000 feet (4,900m)    Hindu Kush    mountains in zero-visibility conditions by two SOAR    MH-47E Chinook helicopters. The    Chinooks were refueled in-flight three times during the 11-hour    mission, establishing a new world record for combat rotorcraft    missions at the time. They linked up with the CIA and Northern    Alliance. Within a few weeks the Northern Alliance, with    assistance from the U.S. ground and air forces, captured    several key cities from the Taliban.[102][107]  
    The U.S. officially launched Operation Enduring Freedom on    7 October 2001 with the assistance of the United    Kingdom. The two were later joined by other    countries.[39][40] The    U.S. and its allies drove the Taliban from power and built    military bases near major cities across the country. Most    al-Qaeda and Taliban were not captured, escaping to neighboring    Pakistan or    retreating to rural or remote mountainous regions.[citation    needed]  
    On 20 December 2001, the United Nations authorized an International    Security Assistance Force (ISAF), with a mandate to help    the Afghans maintain security in Kabul and surrounding areas.    It was initially established from the headquarters of the    British 3rd Mechanised    Division under Major General John McColl, and for its first years    numbered no more that 5,000.[108]    Its mandate did not extend beyond the Kabul area for the first    few years.[109] Eighteen    countries were contributing to the force in February 2002.  
    At the Bonn    Conference in December 2001, Hamid Karzai was selected to head the    Afghan Interim    Administration, which after a 2002 loya    jirga in Kabul    became the Afghan Transitional    Administration. In the popular elections of    2004, Karzai was elected president of the country, now    named the Islamic Republic of    Afghanistan.[41]  
    In August 2003, NATO became involved as an alliance, taking the    helm of the International    Security Assistance Force.[42]    One portion of U.S. forces in Afghanistan operated under NATO    command; the rest remained under direct U.S. command. Taliban    leader Mullah Omar reorganized the movement, and    in 2003, launched an insurgency against the government    and ISAF.[43][44]  
    After evading coalition forces throughout mid-2002, Taliban    remnants gradually regained confidence and prepared to launch    the Taliban insurgency that Omar had    promised.[110] During September, Taliban    forces began a jihad recruitment drive in Pashtun areas in    Afghanistan and Pakistan. Pamphlets distributed in secret    appeared in many villages in southeastern Afghanistan called    for jihad.[111]  
    Small mobile training camps were established along the border    to train recruits in guerrilla warfare.[112] Most were drawn from tribal    area madrassas in Pakistan. Bases, a few with as many as 200    fighters, emerged in the tribal areas by the summer of 2003.    Pakistani will to prevent infiltration was uncertain, while    Pakistani military operations proved of little use.[113]  
    The Taliban gathered into groups of around 50 to launch attacks    on isolated outposts, and then breaking up into groups of 510    to evade counterattacks. Coalition forces were attacked    indirectly, through rocket attacks on bases and improvised explosive devices.  
    To coordinate the strategy, Omar named a 10-man leadership    council, with himself as its leader.[113] Five    operational zones were assigned to Taliban commanders such as    Dadullah, who took charge in Zabul province.[113]    Al-Qaeda forces in the east had a bolder strategy of attacking    Americans using elaborate ambushes. The first sign of the    strategy came on 27 January 2003, during Operation Mongoose, when a band of    fighters were assaulted by U.S. forces at the Adi Ghar cave    complex 25km (15mi) north of Spin Boldak.[114] 18    rebels were reported killed with no U.S. casualties. The site    was suspected to be a base for supplies and fighters coming    from Pakistan. The first isolated attacks by relatively large    Taliban bands on Afghan targets also appeared around that time.  
    As the summer continued, Taliban attacks gradually increased in    frequency. Dozens of Afghan government soldiers, NGO humanitarian    workers, and several U.S. soldiers died in the raids,    ambushes and rocket attacks. Besides guerrilla attacks, Taliban    fighters began building up forces in the district of Dai    Chopan in Zabul Province. The Taliban decided to    make a stand there. Over the course of the summer, up to 1,000    guerrillas moved there. Over 220 people, including several    dozen Afghan police, were killed in August 2003. In late August    2005, Afghan government forces attacked, backed by U.S. troops    with air support. After a one-week battle, Taliban forces were    routed with up to 124 fighters killed.  
    On 11 August 2003, NATO assumed control of ISAF.[109] On 31 July    2006, ISAF assumed command of the south of the country, and by    5 October 2006, of the east.[115] Once    this transition had taken place, ISAF grew to a large coalition    involving up to 46 countries, under a U.S. commander.  
    From January 2006, a multinational ISAF contingent started to    replace U.S. troops in southern Afghanistan. The British 16th Air    Assault Brigade (later reinforced by Royal Marines)    formed the core of the force, along with troops and helicopters    from Australia, Canada and the Netherlands. The initial force    consisted of roughly 3,300 British,[116] 2,300    Canadian,[117] 1,963 Dutch,    300 Australian,[118] 290    Danish[119] and 150    Estonian    troops.[120] Air    support was provided by U.S., British, Dutch, Norwegian and    French combat aircraft and helicopters.  
    In January 2006, NATO's focus in southern Afghanistan was to    form Provincial Reconstruction    Teams with the British leading in Helmand while the    Netherlands and Canada would lead similar deployments in    Orzgn and Kandahar, respectively. Local Taliban figures    pledged to resist.[121]  
    Southern Afghanistan faced in 2006 the deadliest violence since    the Taliban's fall. NATO operations were led by British,    Canadian and Dutch commanders. Operation Mountain Thrust was    launched on 17 May 2006, with. In July, Canadian Forces,    supported by U.S., British, Dutch and Danish forces, launched Operation    Medusa.  
    A combined force of Dutch and Australians    launched a successful offensive    between late April to mid July 2006 to push the Taliban out of    the Chora and Baluchi areas.  
    On 18 September 2006 Italian special forces of Task Force 45    and airborne troopers of the 'Trieste' infantry regiment of the    Rapid Reaction Corps composed of Italian and Spanish forces,    took part in 'Wyconda Pincer' operation in the districts of    Bala Buluk and Pusht-i-Rod, in Farah province. Italian forces    killed at least 70 Taliban. The situation in RC-W then    deteriorated. Hotspots included Badghis in the very north and    Farah in the southwest.  
    Further NATO operations included the Battle of    Panjwaii, Operation Mountain Fury and    Operation Falcon Summit. NATO    achieved tactical victories and area denial, but the Taliban    were not completely defeated. NATO operations continued into    2007.  
    In January and February 2007, British Royal Marines mounted    Operation Volcano to clear insurgents    from firing-points in the village of Barikju, north of Kajaki.[122] Other major    operations during this period included Operation    Achilles (MarchMay) and Operation Lastay Kulang. The UK    Ministry of Defence announced its intention to bring British    troop levels in the country up to 7,700 (committed until    2009).[123] Further    operations, such as Operation Silver and Operation Silicon, took place to keep    up the pressure on the Taliban in the hope of blunting their    expected spring offensive.[124][125]  
    In February 2007, Combined Forces    Command-Afghanistan inactivated. Combined Joint Task Force    76, a two-star U.S. command headquartered on Bagram    Airfield, assumed responsibility as the National Command    Element for U.S. forces in Afghanistan.[126]    Combined Security Transition Command-Afghanistan, or CSTC-A,    the other two-star U.S. command, was charged with training and    mentoring the Afghan National Security Forces.  
    On 4 March 2007, U.S. Marines killed at least 12 civilians and    injured 33 in Shinwar district, Nangrahar,[127] in a response to a bomb    ambush. The event became known as the "Shinwar massacre".[128] The    120 member Marine unit responsible for the attack were ordered    to leave the country by Army Major General Frank Kearney,    because the incident damaged the unit's relations with the    local Afghan population.[129]  
    Later in March 2007, the US added more than 3,500 troops.  
    On 12 May 2007, ISAF forces killed Mullah Dadullah. Eleven    other Taliban fighters died in the same firefight.  
    During the summer, NATO forces achieved tactical victories at    the Battle of Chora in Orzgn, where Dutch    and Australian ISAF forces were deployed.  
    On 16 August, eight civilians including a pregnant woman and a    baby died when Polish soldiers shelled the village of    Nangar Khel, Paktika Province. Seven soldiers have been    charged with war crimes.  
    On 28 October about 80 Taliban fighters were killed in a    24-hour battle in Helmand.[130]  
    Western officials and analysts estimated the strength of    Taliban forces at about 10,000 fighters fielded at any given    time. Of that number, only 2,000 to 3,000 were highly    motivated, full-time insurgents. The rest were part-timers,    made up of alienated, young Afghans, angered by bombing raids    or responding to payment. In 2007, more foreign fighters came    than ever before, according to officials. Approximately 100 to    300 full-time combatants are foreigners, usually from Pakistan,    Uzbekistan, Chechnya, various Arab countries and perhaps even    Turkey and western China. They were reportedly more fanatical    and violent, often bringing superior video-production or    bombmaking expertise.[131]  
    On 2 November security forces killed a top-ranking militant,    Mawlawi Abdul Manan, after he was caught crossing the border.    The Taliban confirmed his death.[132] On 10    November the Taliban ambushed a patrol in eastern Afghanistan.    This attack brought the U.S. death toll for 2007 to 100, making    it the Americans' deadliest year in Afghanistan.[133]  
    The Battle of Musa Qala took place in    December. Afghan units were the principal fighting force,    supported by British forces.[134] Taliban    forces were forced out of the town.  
    Admiral Mike Mullen, Chairman of the Joint    Chiefs of Staff, said that while the situation in    Afghanistan is "precarious and urgent", the 10,000 additional    troops needed there would be unavailable "in any significant    manner" unless withdrawals from Iraq are made. The priority was Iraq first,    Afghanistan second.[135]  
    In the first five months of 2008, the number of U.S. troops in    Afghanistan increased by over 80% with a surge of 21,643 more    troops, bringing the total from 26,607 in January to 48,250 in    June.[136]    In September 2008, President Bush announced the withdrawal of    over 8,000 from Iraq and a further increase of up to 4,500 in    Afghanistan.[137]  
    In June 2008, British prime minister Gordon Brown    announced the number of British troops serving in Afghanistan    would increase to 8,030 a rise of 230.[138] The same month, the UK lost    its 100th serviceman.[139]  
    On 13 June, Taliban fighters demonstrated their ongoing    strength, liberating all prisoners in Kandahar jail. The    operation freed 1200 prisoners, 400 of whom were Taliban,    causing a major embarrassment for NATO.[140]  
    On 13 July 2008, a coordinated Taliban attack was    launched on a remote NATO base at Wanat in Kunar province. On 19 August, French    troops suffered their worst losses in Afghanistan in an ambush.[141]    Later in the month, an airstrike targeted a Taliban    commander in Herat province and killed 90 civilians.  
    Late August saw one of NATO's largest operations in Helmand,    Operation Eagle's Summit, aiming    to bring electricity to the region.[142]  
    On 3 September, commandos, believed to be U.S. Army Special Forces, landed    by helicopter and attacked three houses close to a known enemy    stronghold in Pakistan. The attack killed between seven and    twenty people. Local residents claimed that most of the dead    were civilians. Pakistan condemned the attack, calling the    incursion "a gross violation of Pakistan's territory".[143][144]  
    On 6 September, in an apparent reaction, Pakistan announced an    indefinite disconnection of supply lines.[145]  
    On 11 September, militants killed two U.S. troops in the east.    This brought the total number of U.S. losses to 113, more than    in any prior year.[146] Several    European countries set their own records, particularly the UK,    who suffered 108 casualties.[22]  
    In November and December 2008, multiple incidents of major    theft, robbery, and arson attacks afflicted NATO supply convoys    in Pakistan.[147][148][149] Transport companies    south of Kabul were extorted for money by the Taliban.[149][150] These incidents    included the hijacking of a NATO convoy carrying supplies in    Peshawar,[148]    the torching of cargo trucks and Humvees east of the Khyber    pass[151] and a    half-dozen raids on NATO supply depots near Peshawar that    destroyed 300 cargo trucks and Humvees in December    2008.[152]  
    An unnamed senior Pentagon official told the BBC that at some    point between 12 July and 12 September 2008, President Bush    issued a classified order authorizing raids against militants    in Pakistan. Pakistan said it would not allow foreign forces    onto its territory and that it would vigorously protect its    sovereignty.[153] In    September, the Pakistan military stated that it had issued    orders to "open fire" on U.S. soldiers who crossed the border    in pursuit of militant forces.[154]  
    On 25 September 2008, Pakistani troops fired on ISAF    helicopters. This caused confusion and anger in the Pentagon,    which asked for a full explanation into the incident and denied    that U.S. helicopters were in Pakistani airspace.  
    A further split occurred when U.S. troops apparently landed on    Pakistani soil to carry out an operation against militants in    the Khyber Pakhtunkhwa Province. 'Pakistan    reacted angrily to the action, saying 20 innocent villagers had    been killed by US troops'.[155]    However, despite tensions, the U.S. increased the use of remotely piloted drone    aircraft in Pakistan's border regions, in particular the    Federally    Administered Tribal Regions (FATA) and Balochistan; as of    early 2009, drone attacks were up 183% since 2006.[156]  
    By the end of 2008, the Taliban apparently had severed    remaining ties with al-Qaeda.[157] According to    senior U.S. military intelligence officials, perhaps fewer than    100 members of al-Qaeda remained in Afghanistan.[158]  
    In a meeting with General Stanley    McChrystal, Pakistani military officials urged    international forces to remain on the Afghan side of the border    and prevent militants from fleeing into Pakistan. Pakistan    noted that it had deployed 140,000 soldiers on its side of the    border to address militant activities, while the coalition had    only 100,000 soldiers to police the Afghanistan side.[159]  
    In response to the increased risk of sending supplies through    Pakistan, work began on the establishment of a Northern    Distribution Network (NDN) through Russia and Central Asian    republics. Initial permission to move supplies through the    region was given on 20 January 2009, after a visit to the    region by General David Petraeus.[160] The first    shipment along the NDN route left on 20 February from Riga, Latvia, then traveled    5,169km (3,212mi) to the Uzbek town of Termez on the Afghanistan    border.[161] In    addition to Riga, other European ports included Poti, Georgia and Vladivostok,    Russia.[162] U.S. commanders hoped that    100 containers a day would be shipped along the NDN.[161] By comparison, 140    containers a day were typically shipped through the Khyber    Pass.[163] By 2011, the NDN handled about    40% of Afghanistan-bound traffic, versus 30% through    Pakistan.[162]  
    On 11 May 2009, Uzbekistan president Islam Karimov    announced that the airport in Navoi    (Uzbekistan) was being used to transport non-lethal cargo into    Afghanistan. Due to the still unsettled relationship between    Uzbekistan and the U.S. following the 2005 Andijon massacre and subsequent    expulsion of U.S. forces from Karshi-Khanabad    airbase, U.S. forces were not involved in the shipments.    Instead, South Korea's Korean Air, which overhauled Navoi's airport,    officially handled logistics.[164]  
    Originally only non-lethal resources were allowed on the NDN.    In July 2009, however, shortly before a visit by new President    Barack    Obama to Moscow, Russian authorities announced that U.S.    troops and weapons could use the country's airspace to reach    Afghanistan.[165]  
    Human rights advocates were (as of 2009) concerned that the    U.S. was again working with the government of Uzbekistan, which    is often accused of violating human rights.[166] U.S. officials promised    increased cooperation with Uzbekistan, including further    assistance to turn Navoi into a regional distribution center    for both military and civilian ventures.[167][168]  
    In January, about 3,000 U.S. soldiers from the 3rd Brigade    Combat Team of the 10th Mountain Division moved    into the provinces of Logar and Wardak. Afghan    Federal Guards fought alongside them. The troops were the first    wave of an expected surge of reinforcements originally ordered    by President Bush and increased by President Obama.[169]  
    In mid-February, it was announced that 17,000 additional troops    would be deployed in two brigades and support troops; the 2nd Marine    Expeditionary Brigade of about 3,500 and the 5th Brigade, 2nd    Infantry Division, a Stryker Brigade with about 4,000.[170] ISAF commander General    David McKiernan had called for as many as    30,000 additional troops, effectively doubling the number of    troops.[171] On 23 September, a classified    assessment by General McChrystal included his conclusion that a    successful counterinsurgency strategy would    require 500,000 troops and five years.[172]  
    In November, Ambassador Karl W.    Eikenberry sent two classified cables to Washington    expressing concerns about sending more troops before the Afghan    government demonstrates that it is willing to tackle the    corruption and mismanagement that has fueled the Taliban's    rise. Eikenberry, a retired three-star general who in 20062007    commanded U.S. troops in Afghanistan, also expressed    frustration with the relative paucity of funds set aside for    development and reconstruction.[173] In    subsequent cables, Eikenberry repeatedly cautioned that    deploying sizable American reinforcements would result in    "astronomical costs" tens of billions of dollars    and would only deepen the Afghan government's dependence on the    United States.  
    On 26 November, Karzai made a public plea for direct    negotiations with the Taliban leadership. Karzai said there is    an "urgent need" for negotiations and made it clear that the    Obama administration had opposed such talks. There was no    formal US response.[174][175]  
    On 1 December, Obama announced at the U.S. Military Academy in West Point    that the U.S. would send 30,000 more troops.[176] Antiwar organizations in the    U.S. responded quickly, and cities throughout the U.S. saw    protests on 2 December.[177] Many    protesters compared the decision to deploy more troops in    Afghanistan to the expansion of the Vietnam War under the    Johnson administration.[178]  
    On 4 September, during the Kunduz Province Campaign a    devastating NATO air raid was    conducted 7 kilometres southwest of Kunduz where Taliban    fighters had hijacked civilian supply trucks, killing up to 179    people, including over 100 civilians.[179]  
    On 25 June US officials announced the launch of Operation    Khanjar ("strike of the sword").[180] About 4000    U.S. Marines from the 2nd Marine    Expeditionary Brigade[181] and 650 Afghan    soldiers[182] participated. Khanjar followed    a British-led operation named Operation Panther's Claw in the    same region.[183] Officials called it the    Marines' largest operation since the 2004 invasion of Fallujah,    Iraq.[181] Operation    Panther's Claw was aimed to secure various canal and river    crossings to establish a long-term ISAF presence.[184]
