War in Afghanistan (2015–present) refers to the period of the war in Afghanistan following the 2001–2014 phase, led by the United States. The U.S.-led war followed the September 11 attacks, aiming to dismantle al-Qaeda and deny it a safe-haven in Afghanistan by removing the Taliban from power. After 2001, the North Atlantic Treaty Organization (NATO) became increasingly involved, eventually running combat operations, under the direction of a U.S. commander. 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, marking the beginning of the new phase of the conflict. The planned partial withdrawal of U.S. troops from Afghanistan, as well as NATO troops, and the transfer of many combat roles from NATO forces to the Afghan security forces occurred between 2011 and 2014. A bilateral security agreement was signed between the US and Afghanistan that would allow NATO troops to remain after the withdrawal date in an advisory and counter-terrorism capacity. The NATO troop presence would amount to approximately 13,000 troops including 9,800 Americans. The relatively small American presence there has been active in executing airstrikes as well as providing close air support for the Afghan forces. Not counting CAS missions, American airstrikes are estimated to have killed 1,400–1,900 militants since January 1, 2015, as well as 75–100 civilians.
