“An Afghan policeman opened fire and tossed a hand grenade on a U.S. military patrol in eastern Afghanistan, killing an American soldier, the U.S. military said Thursday. It was the second time in less than a month that an Afghan officer has killed a U.S. soldier, raising concerns that militants may have infiltrated the Afghan police force. In the latest attack, a police officer on a tower attacked the American foot patrol in Bermel district of the eastern Paktika province, the military said. The troops returned fire on the tower, killing the policemen. The military said it was investigating the attack.” (10/16/08)
