Libya rebels overrun Gaddafi HQ, say he's 'finished'

TRIPOLI (Reuters) - Libyan rebels sacked Muammar Gaddafi's Tripoli bastion, seizing weapons and smashing symbols of a 42-year dictatorship whose demise will transform Libya and send a warning to other Arab autocrats facing popular uprisings.

Gaddafi said his withdrawal from his Bab al-Aziziya headquarters in the heart of the capital was a tactical move after it had been hit by 64 NATO air strikes and he vowed "martyrdom" or victory in his fight against the alliance.
