At least 12 militants were killed Friday in an airstrike carried out by the NATO-led International Security Forces (ISAF) in Afghanistan's eastern province of Nuristan, officials said.
The ISAF killed more than a dozen militants after they attacked an outpost in Nuristan, a coalition statement said.
The coalition forces took help of combat helicopters to locate the militants after an ISAF combat outpost received mortar fire, it said.
More than a dozen militants were killed and two vehicles belonging to the militants were destroyed.
A witness said that 12 civilians were also killed in the attack in Kamdesh district of the province, where the US-led coalition forces are based.
Around 2,000 people, including 700 civilians, have been killed in insurgency related violence so far this year in Afghanistan.
