Airstrikes killed several militants who attacked a patrol in southern Afghanistan, AP quoted the U.S.-led coalition as saying Thursday. A coalition helicopter also crash-landed in the east without causing serious injuries, it said. The warplanes attacked after insurgents fired on Afghan and U.S.-led forces on patrol in the Maywand district of Kandahar province on Wednesday, a coalition statement said. The insurgents were killed with «several precision airstrikes,» it said. No government or coalition troops were reported injured.
