TRIPOLI, Libya (AP) -- Fresh fighting has erupted in Tripoli hours after Moammar Gadhafi's son turned up free to thwart rebel claims he had been captured and to rally supporters.
Rebels and forces loyal to the Libyan leader waged fierce street battles Tuesday, a day after opposition fighters swept into the capital with relative ease, claiming to have most of it under their control.
Thick clouds of gray and white smoke filled the sky as heavy gunfire and explosions shook several districts of the city of 2 million people. Some of the heaviest fighting was around Gadhafi's Bab al-Aziziya main compound and military barracks.
The reappearance of Seif al-Islam in Tripoli appears to have energized forces loyal to Gadhafi.
