Defiant Gaddafi promises 'martyrdom or victory'

Colonel Gaddafi has reportedly made a defiant speech on Libyan radio, just hours after his compound in Tripoli came under attack from rebels.

His whereabouts remain unknown, but according to a pro-Gaddafi television channel, the 69-year-old promised "martyrdom or victory" in his fight against the rebels and Nato forces.

Meanwhile opposition supporters continue to celebrate in Tripoli's central square, although there are reports of sporadic resistance from pro-Gaddafi fighters in parts of the capital.
