U.S. and Afghan troops fired warning shots after more than 1,000 protesters chanting "Die America!" threw stones at a U.S. military convoy and at the main U.S. base in Afghanistan to demand the release of eight villagers detained in a raid.
Afghan troops used batons to beat back the protesters as they tried to push down the base's outer gate, as black smoke from burning tires billowed across the area.

The soldiers used sticks to beat back the protesters and several fired into the air with their assault rifles as they shouted at the protesters to go home. Most dispersed.
