U.S.-led airstrike kills Pakistani troops

U.S.-led coalition forces along the volatile Afghan border launched an airstrike that killed 11 Pakistani paramilitary troops, Pakistan’s army said Wednesday. The military condemned it as an act of aggression within Pakistan’s border that “hit at the very basis of cooperation” in the war on terrorism. The coalition said it used artillery and aerial drones against attackers who opened fire on forces operating inside Afghanistan. It said coalition forces did not enter Pakistan.
