The airstrike during a battle between Taliban militants and a joint force of U.S. and Afghan forces killed a U.S. civilian adviser.

Wasifullah Wasify, a government official in Kunar province, said Sunday that the airstrike occurred the day before during a fierce gun battle between Taliban militants and a joint force of U.S. and Afghan forces.
He says 10 children and one woman were killed when the airstrike destroyed a house in a remote area of the province.
A U.S. civilian adviser also was killed in Saturday's fighting.
