Three U.S. defense contractors helping train Afghan air force personnel were gunned down at the Kabul airport in what military sources says was an “insider attack.” The Taliban has claimed responsibility for the killings Thursday night.
The attacker in the Thursday incident was a Taliban agent who “had penetrated into the security forces and was waiting for such a target for a long time,” a spokesman for the group, Zabiullah Mujahid, said Friday.
The airport in the Afghan capital is heavily guarded, with one section devoted to commercial aircraft and another area set aside for a NATO contingent.
At least nine people were killed earlier Thursday in the country`s east when a suicide bomber struck at a funeral for victims of a roadside bomb attack.
An increase in so-called insiders attacks in Afghanistan eroded trust between government forces and their international allies in the final years of the combat mission that ended in 2014, prompting foreign forces to scale back interaction with Afghans.
It was unclear whether the Afghan national who authorities said was killed in the attack was the shooter or someone else who worked on the military complex at the airport, where the killings occurred.
