Rebels in the Nafusa Mountains of western Libya have made substantial gains in recent weeks against forces loyal to Moammar Gadhafi. But the fighting has prompted a growing humanitarian crisis in this isolated region southwest of Tripoli.
Fighting across Libya has been characterized by a lack of sophisticated weapons. Pointing to a rusted rifle, a fighter on the front line of a recent battle in the mountains said it's "more than 100 years" old. "Our grandfathers before us use it in front of Italian army in 1911," he said.
