Gaddafi's son Saif al-Islam 'was not arrested'

Fighting has flared in two key areas of the Libyan capital, Tripoli, for a third day as rebel fighters battle forces loyal to Col Muammar Gaddafi.

Gunfire and explosions have been heard near a hotel held by government troops, as well as the area around the Libyan leader's Bab al-Aziziya compound.

Overnight, Col Gaddafi's son Saif al-Islam appeared in public, disproving reports that he had been captured.

He insisted the government had "broken the backbone" of the rebel offensive.
