About 20 Taliban fighters were killed in a battle with Afghan and U.S.-led forces near a key military supply route in western Afghanistan, a provincial official said Saturday. Younus Rasouli, deputy governor of Farah province, said police attacked a village in Bala Buluk district Friday after being informed that Taliban fighters had ordered residents out and taken it over to use as a base. The police called in air support from the U.S.-led coalition during the gun battle, Rasouli was quoted as saying by the Associated Press. Coalition spokesman 1st Lt. Nathan Perry confirmed that fighter aircraft engaged in combat in Bala Buluk on Friday for about an hour. He said there were no coalition casualties but did not provide further details.
