The website Quryna, which has ties to Seif Al-Islam Qaddafi, said many state executives will be replaced when the congress returns.

Four days of pro-democracy protests in Libya have pushed for an end to Qaddafi's rule and have left dozens of demonstrators dead after clashes with security forces nationwide. There was another violent demonstration Friday in the eastern city of Benghazi, Libya's second-largest.

Gamal Bandour, a judge in Benghazi, said marchers clashed with security forces after a funeral where the bodies of 15 protesters shot dead Thursday were buried. On their way back from the service, protesters set fire to government buildings and police stations.

Quryna said security personnel fired on the Benghazi protesters, killing 13 of them. "The security forces were forced to use live bullets to stop the protesters, when their protests turned violent and aggressive as they set fire to police stations in the city, attacked administrative buildings and set fire to police vehicles including six in front of Jalaa Hospital," it said.

The site also said 1,000 inmates at a prison in Benghazi attacked guards and escaped, though three of them were shot dead by guards.

Two people in Benghazi told Reuters that Saadi Qaddafi, a businessman son of the Libyan leader, had taken over command of the city. He holds senior military rank and was briefly employed as a player by Italian professional football clubs.

Two Swiss-based exile groups said anti-government forces, joined by defecting police, were battling with security forces for control of the town of Al-Baida, 200 km northeast of Benghazi and scene of deadly clashes this week. An opposition activist in Al-Baida told Reuters the town was calm after the burial of 14 people killed in Thursday's protests. "A massacre took place here yesterday," said the man.

A hospital official told The Associated Press that his facility was treating about 500 wounded — some in the parking lot for lack of beds. "We need doctors, medicine and everything," he said.

France announced Friday it had suspended exports of security equipment bound for Libya and Bahrain after anti-government protesters were killed in both countries.
