Libyan rebels advance towards Tripoli - spokesman
"We are on the southern and western outskirts of Bir al-Ghanam," Juma Ibrahim, a rebel spokesman in the nearby town of Zintan, said by telephone.
"There were battles there most of yesterday. Some of our fighters were martyred and they (government forces) also suffered casualties and we captured equipment and vehicles. It's quiet there today and the rebels are still in their positions," he said.
