A Libyan fighter says rival militias are fighting near a former major military camp of Moammar Gaddafi's regime.
Sunday's clashes marked the fourth day of confrontations between the two groups, the most sustained violence since the fall of Gadhafi's regime last month. The fighting has killed four people so far.
Journalists were kept from the scene, but the sound of gunfire and rocket-propelled grenades could be heard in the distance. The camp is located along a highway about midway between the capital of Tripoli and the coastal city of Zawiya, some 50 kilometers (30 miles) to the west. Mohammed al-Hadwash, a local commander of fighters from Tripoli, says gunmen from Zawiya and the nearby town of Warshefana are fighting for control of the camp.
