"Two former Libyan rebel factions clashed Tuesday in hours of gunbattles in central Tripoli that left five fighters dead, a Tripoli military council official said. Former rebels of Tripoli and a separate group of fighters from the city of Misrata fought with machine guns, rocket-propelled grenades and anti-aircraft guns. Col. Walid Shouaib, a member of Tripoli Military Council, said the clashes were triggered by arrest of a Misrata fighter on New Year's Eve by Tripoli fighters. He was suspected of robbery and the Misrata fighters were trying to free him. A Misrata military council member, Mohammed al-Gressa, said he feared a civil war. He said a meeting was taking place between commanders of ex-rebels and the Tripoli military council. "I am not optimistic because blood has been spilled," he told The Associated Press. "I feel this looks like a civil war." Others said the clashes were not that serious."
