An Afghan official has said that US troops opened fire after their convoy was attacked in eastern Nangarhar province, killing three civilians.
Attahullah Khogyani, spokesman for the provincial governor, says a convoy was en route to a mission Sunday night when it was struck by a roadside bomb. Khogyani says the troops reacted by opening fire, killing a father and two sons.
Douglas High, a spokesman for the NATO mission in Afghanistan, confirmed that a convoy transporting both US and Afghan soldiers was struck by a roadside bomb and attacked with small arms fire.
High said in a statement that the soldiers returned fire in self-defense and there were no US casualties.
"We have not received any official allegations of civilian casualties," High said.
