On Thursday, three US contractors were shot to death at the Kabul Airport. The Taliban has claimed responsibility for the attack.
From Fox News:
Just days after an Obama administration official went to great pains to explain that the Taliban is not considered a terrorist group, the Afghan-based organization on Friday to credit for an attack that killed three American contractors and said it was carried out by a fighter who had infiltrated Afghanistan's security forces.
The attack came Thursday evening at a military base at Kabul's international airport, and also left one Afghan dead. The Taliban's claim of responsibility came in a message on Friday from spokesman Zabihullah Mujahid, who identified the attacker as a man named "Hessanullha," from Laghman province, just east of Kabul. Hessanullha "penetrated into the security forces and was waiting for such a target for a long time," Mujahid said.
