KABUL -- Residents of the southeastern Afghan city of Khost are reporting heavy gunfire and explosions near the main police station and other government buildings.
The firing erupted Saturday afternoon, and residents were unable to move about in safety.
Provincial council member Tajaly Khan Saber told The Associated Press that it was not possible to determine the number of casualties.
An Afghan official says the main targets appear to be the police headquarters, attorney general's office, courts and a local bank branch.
Last May, 11 Taliban suicide bombers struck government buildings in Khost, killing 20 people and wounding three Americans.
It's not clear if U.S. troops are involved in the current fighting.
