Libya-Fresh fighting has broken out between rival Libyan militias on the outskirts of the capital, Tripoli, after at least 43 people died while about 500 people were wounded in clashes on Friday.

The Prime Minister Ali Zeidan has also confirmed that fresh fighting had been taking place in Tajoura on Saturday.

The latest violence in the suburb of Tajoura involves local militiamen against incoming fighters from Misrata.

Friday's clashes occurred after protesters marched on the headquarters of the Misrata militia to demand that it leave Tripoli, and were fired upon.

Although Mr Zeidan said the protest march had been "peaceful and came under fire when it entered Ghargour".

However, Libya's al-Ahrar television reportedly quoted Taher Basha Agha, the head of the Misrata militia at Ghargour, as saying that the protesters were armed.

"It was not a peaceful demonstration. They carried light arms and shot at us," he was quoted as saying.

The government is struggling to contain militias who control parts of Libya.

Reports stated that Ali Zeidan urged all sides to "exercise maximum restraint", adding: "No forces from outside Tripoli should attempt to enter the city because the situation is very tense and could escalate further."

 "The coming hours and days will be decisive for the history of Libya and the success of the revolution." He said.

Government-linked militias have set up checkpoints across the capital as security is tightened for the funerals of many of those killed on Friday.

The militia was involved in clashes in the capital last week which left two people dead.

There have been increasing demands from civilians that the militias - which emerged during the 2011 revolution - disband or join the army, in line with an end-of-year deadline set by the interim government in Tripoli.

Some militiamen have been given salaries and taken into the government security forces but many still remain loyal to their own commanders.

Last month, Mr Zeidan was briefly seized by a militia group in Tripoli.

Two years after the overthrow of Col Muammar Gaddafi, Libya still has no constitution and divisions between secular and Islamist forces have paralysed parliament.
