Several anti-Gaddafi fighters from the port city of Zawiyah said at least two of their comrades were killed by fire from an armed tribal group which was in control of an area at Imaya, between Zawiyah and the capital. At least two had been killed on Friday after tension flared between the two groups.
As gunfire continued nearby, Nidal al-Akrout, a fighter from Zawiyah loyal to the Libyan interim government, told Reuters at the scene that two men from his brigade had been killed.
Issam al-Tarhouni, another fighter from Zawiyah, said by telephone that he had seen at least three people dead.
