MAZAR-E-SHARIF, Afghanistan?Hundreds of Osama bin Laden’s foreign legion were killed after staging an uprising with smuggled arms in a northern alliance prison Sunday, officials said. U.S. airstrikes helped quash the daylong insurrection.

A U.S. special forces soldier inside the fortress was taped by a German television crew saying an American may have been killed in the fighing.

U.S. officials in Washington, however, would not comment on whether there were Americans inside the Qalai Janghi fortress or whether any had been hurt or killed.

The fighters, about 300 Chechens, Pakistanis and Arabs who surrendered Saturday from the besieged city of Kunduz, had smuggled weapons under their tunics into the fortress and tried to fight their way out, Pentagon spokesman Lt. Col. Dan Stoneking said.

The alliance said most of the prisoners were killed.
