An Associated Press reporter with the rebels saw them take over the base of the Khamis Brigade, 16 miles west of the capital, on Sunday. The base has been defending Qaddafi's stronghold of Tripoli. After a brief gunbattle, Qaddafi's forces fled.
Inside the base, hundreds of rebels cheered wildly and danced, raising the rebel flag on the front gate of a large, gray wall enclosing the compound. They seized large stores of weapons from the base, driving away with truckloads of whatever arms they could get their hands on. One of the rebels carried off a tube of grenades, while another carted off two mortars.
"Anti-Qaddafi forces have had momentum on their side for some time," a U.S. senior administration official told Fox News on Sunday. "If Tripoli eventually falls to the rebels, Qaddafi's already limited options would become even more limited. Pressure on him and his shrinking circle of loyalists has to be taking a seriously toll."
NATO has reportedly been bombing Qaddafi's Tripoli compound continuously, though no casualties have been reported yet.
Mukhtar Lahab, a rebel commander closing in on Tripoli and a former captain in Qaddafi's army, said relatives inside the capital reported mass protests in four neighborhoods known to be sympathetic to the opposition: Fashlum, Souk al-Jouma, Tajoura and Janzour. He said mosques there were rallying residents with chants of "Allahu Akbar" or "God is great," broadcast on loudspeakers.
The capture of Tripoli would almost certainly herald the end of Qaddafi's regime, more than 40 years after the maverick leader seized power in a military coup that toppled the monarchy of the vast North African nation.
