An Afghan soldier opened fire Thursday on his North Atlantic Treaty Organization trainers, killing one and wounding several others at a military training facility and base in the eastern province of Paktia, according to officials cited by Agence France Presse. NATO's International Security Assistance Force (ISAF) said the attacker, described as "wearing Afghan national security forces uniform", was killed in return fire from other troops on the ground. An Afghan soldier shot three United States soldiers to death during a training exercise in Paktia last Saturday.
Attacks of this nature, locally known as "insider" or "green on blue" are common in Afghanistan where Afghan troops, some of them reportedly affiliated to insurgent groups, turn on NATO and US allies. Paktia is known to be one of the hotbeds of the Taliban insurgency. The attacks have killed scores of US-led troops, breeding mistrust and undermining efforts to train local forces before NATO combat troops withdraw next year.
