Libyan defence minister in restive Bani Walid for talks
Libya's defence minister has arrived in Bani Walid, a former stronghold of the Gaddafi regime, after four people were killed in fighting there on Monday.
Osama al-Juwali wants to negotiate with militiamen who drove those loyal to the National Transitional Council into the surrounding desert, officials say.
Locals have told the BBC 90% of the town is under the militiamen's control.
In case Mr Juwali is unsuccessful, NTC forces armed with artillery and rockets have gathered outside, ready to attack.'Iron fist'
However, one commander was overheard telling his men that they were there "for the purposes of reconciliation, not fighting".
At the scene
There were no green flags flying from the roofs of houses in Bani Walid. But nor were there many of the red, black and green banners of the revolutionaries who now control the country. Or most of it.
The government has played down accusations that Gaddafi loyalists were behind the clashes that drove out NTC forces on Monday. But it has nevertheless sent sizeable military reinforcements towards the town.
A long convoy of military vehicles snaked along the road running through the Nefusa Mountains towards Bani Walid. There were hundreds of men, fighters from various militias from across western Libya, but all loyal to the government.
Their commanders said they were not going to fight but to keep the peace. They too played down the link to the former regime. But, inside Bani Walid, behind the locked doors of his office, one local official said the town was full of Gaddafi loyalists.
"These people think that one day they will control Libya again," he said. "They have money and they have weapons."
On Tuesday, the head of Bani Walid's council, Mubarak al-Fatamni, said that forces loyal to the new government were attacked on 23 January in a "barbaric manner" by members of the "remnants of the Gaddafi regime".
Mr Fatamni said the green flag used by Libya during Col Muammar Gaddafi's rule had been flown over the town for a short time on Monday.
But spokesmen for the interim prime minister and defence ministry told the BBC the dispute was a local one, involving rival militias.
Later, Mr Juwali warned that forces loyal to the NTC would "strike with an iron fist" against anyone who posed a threat to Libyan security.
On Wednesday, a member of the local council, Abdul Aziz al-Jumaili, told the Reuters news agency that he had been speaking to the defence minister "to find a solution to this problem".
Mr Jumaili said a "peacekeeping force" comprised of units of former rebel fighters loyal to the NTC and drawn from other towns in the region had set up checkpoints on the outskirts of Bani Walid.
The BBC's Gabriel Gatehouse, who is on the outskirts of Bani Walid, says that for the moment the NTC is describing the recent clashes as a local problem rather than an organised pro-Gaddafi counter revolution.Civil war danger
The NTC says it hopes order can be restored through negotiation, but judging by the force now gathering outside the town it looks like they are keeping their military options open, our correspondent adds.
This is the latest in a series of clashes between rival armed groups, three months after the official end of the revolution that ousted Col Gaddafi.
Earlier this month, armed clashes between militias in the towns of Assabia and Gharyan left 12 dead and about 100 injured.
Libya's interim leader, Mustafa Abdul Jalil, has warned of the dangers of a civil war if the country's militias are not disarmed.
