Rebel Libyan troops abandon bases
Fresh footage has emerged of Libyan military bases abandoned by troops who have joined protests against Moammar Gaddafi. Tobruk is one of many cities across the east where anti-Gaddafi demonstrators have risen up and overwhelmed government buildings and army bases. In many cases the protestors have been joined by local army units – fed up and frustrated they claim by years of mistreatment and abuse. According to some media reports, more than a thousand soldiers have deserted the military barracks, handing over all the weaponry and munitions to the rebels.
