What appears to be the final battle for the pro-Gaddafi stronghold of Bani Walid continues, with NATO air strikes helping Libyan fighters trying to capture the town.
There has been stiff resistance, however, after the deadline given to the Gaddafi loyalists to surrender expired on Saturday.
Forces of the ruling Transitional National Council say they advanced to within 500 metres of the town centre.
But they then pulled back shortly before NATO aircraft struck at least seven times at Gaddafi positions around the town.
It is understood about 1,000 Gaddafi soldiers are defending Bani Walid, far more than the 150 previously estimated.
Heavy fighting was also reported around the other Gaddafi stronghold of Sirte on Friday.
