Kabul airport attack worst US loss in Afghanistan since 2011
The 13 US military troops killed in the bombing attack on Kabul airport Thursday amounted to the worst single-day loss for the Pentagon in Afghanistan since 2011.
The US Defense Department said 13 were killed after two suicide bombers deployed by the Afghanistan branch of the Islamic State group detonated their bombs by a key gate into the airport and at a nearby hotel used for staging evacuees.
The initial toll was 12, which increased when an additional service member died from his wounds.
Ten of those killed and several wounded were US Marines, Marine Corps spokesman Major Jim Stenger said in a statement.
The two-decade war has cost 1,909 US military lives in combat. The heaviest losses came on August 6, 2011, when insurgents shot down a Chinook transport on a nighttime mission in Wardak province southwest of Kabul.
Thirty US American service members, including 22 Navy SEALs special operations troops, were killed in the crash, as well as eight Afghans and a US military dog.
Prior to that, the worst single-day toll also involved a helicopter. On June 28, 2005, three Navy SEALs were killed in a firefight after being flown in to the mountains of the eastern Kunar province.
A helicopter loaded with reinforcements that was sent to help one SEAL still alive on the ground and recover the bodies of the three was shot down, killing 16 on board.
Other major losses include a firefight between scores of Taliban fighters and US troops in Wanat in Nurestan province in July 2008, which saw nine US troops killed.
Fifteen months later, in October 2009, eight Americans died in a similar battle with hundreds of Taliban fighters in Kamdesh, also in Nurestan province.
The war has also seen high tolls from attacks by perceived allies on the Americans.
On April 27, 2011 eight members of the US Air Force and one US civilian were shot dead in Kabul airport by an Afghan pilot.
And on December 30, 2009, a "triple-agent" whom US intelligence thought was on their side killed seven CIA officers and contractors, along with two others, at a CIA facility in eastern Afghanistan known as Camp Chapman.
