KABUL, Afghanistan (AP) – A provincial governor says at least four civilians were killed when their bus was caught in the crossfire during a battle between insurgents and U.S. forces in central Afghanistan.

Wardak Gov. Halim Fidai says at least 10 other passengers were wounded in the shootout Friday morning. He says he has no reports of casualties from either the insurgents or the U.S. military. An Associated Press cameraman saw the bullet-ridden bus later Friday. The vehicle was cordoned off by U.S. troops, who were patrolling the area. The U.S. military referred inquiries to NATO’s International Security Assistance Force. A spokesman with ISAF said they were still waiting for information on the incident and declined to comment.
