A senior Afghan official says U.S. and Afghan forces killed about 50 Taleban insurgents Monday in southern Uruzgan province.

Provincial Governor Jan Mohammad Khan said a major Taleban ammunition depot was destroyed in the operation, and that some 25 fighters were captured.

Meanwhile, U.S. soldiers fired warning shots outside the U.S. military headquarters at Bagram Air Base Tuesday, where several hundred Afghans gathered to demand the release of eight villagers arrested in an overnight raid.

The U.S. military said the shots were fired after some protesters threw stones at military vehicles and tried to push down the base's outer gate.

It said the men were arrested at a compound in Bagram village after troops discovered bomb-making materials there, and that those detained were suspected of planning attacks against U.S.-led forces.
