KABUL, Afghanistan – Afghan officials say at least seven people have been killed in protests around the country against the burning of Korans at a U.S. air base.

The violence Friday raised the total number of people killed in the days of violence to 20.

The governor's office in western Herat province said six died in three incidents there. Three people were killed when a truck full of ammunition exploded after protesters set it ablaze. Three others died in two separate incidents when armed men among the protesters exchanged gunfire with security forces.

Officials said another protester died when Afghan security forces fired in the air to prevent demonstrators from storming a Hungarian base in the north.
