SIRTE, Libya (AFP) - Anti-Gaddafi fighters launched an all-out assault on Wednesday against the ousted strongmans remaining holdouts, now pinned into a small corner of his hometown Sirte. The fighting was concentrated in the outer streets of Sirtes Number Two neighbourhood, with both sides trading heavy gunfire and bombarding each other with mortar shells. Ali al-Rikabi, field commander of the National Transitional Council (NTC), Libyas new rulers, said fighting was raging in four or five streets of the neighbourhood. It is intense and we have exchanges of gunfire, he said, as an AFP reporter saw wounded NTC fighters being hurried out towards a field hospital. The bodies of two NTC fighters killed in Number Two district were taken to an emergency field clinic, an AFP correspondent in the city said, along with at least 25 wounded. Medics said at least 11 NTC fighters were killed and 95 wounded on Tuesday alone in the battle to subdue the last pockets of support for Moamer Gaddafi in Sirte. Dozens of vehicles massed early afternoon in the west of Number Two district, ready to follow a bulldozer and a tank deeper into the district. According to Essam Baghhar, a field commander of the NTCs Zintan Brigade, only Number Two neighbourhood in the Mediterranean city was still being held by Gaddafis forces after NTC fighters overran the adjoining Dollar district late on Tuesday. The Dollar neighbourhood was liberated last night and now the fight is in Number Two neighbourhood, Baghhar said. He added that loyalist forces had been pushed into an area of Number Two neighbourhood less than one square kilometre (0.4 square mile) in size. We have captured many snipers in the past two days, including two women snipers, the commander said. One fighter, who gave his name only as Walid, said NTC forces had captured a weapons store of the pro-Gaddafi fighters. This will drain them of their supplies of arms and ammunition, he said. The fighting is still intense. It is in a small area but it is intense. Sirte once had 100,000 inhabitants, almost all of whom have fled, while fierce artillery battles and heavy gunfire over the past month have not left a single building intact, while looting has become commonplace. Among those killed on Tuesday was Mustafa bin Dardef, a popular field commander with the Zintan Brigade, who was hit by a mortar round. A businessman in Benghazi before he joined the uprising, he leaves a son and four daughters. Gaddafi was toppled in August when NTC fighters overran his headquarters in the capital Tripoli. He has since gone into hiding, with some NTC officials believing he could be in Sirte, making a last stand. However, most believe he is hiding out in Libyas vast southern deserts. NTC leaders have said that once Sirte is fully under their control they will declare Libya free of Gaddafis 42-year autocratic rule and set about forming an interim authority ahead of elections. In the desert oasis of Bani Walid, 170 kilometres (100 miles) southeast of Tripoli, the red, black and green flag of the new government was raised after the only other remaining holdout was captured on Monday. NTC forces Tuesday paraded through the streets in armed pick-up trucks and filled the central square, shouting Allahu Akbar (God is greatest) and letting off deafening bursts of celebratory machine-gun fire. NATO said it was not yet ready to end to its mission over Libya despite the advances made by NTC forces. It is premature to set a timetable now, NATO spokeswoman Carmen Romero said in Brussels. We are very close to the end, but there are still threats to the civilian population. In its latest operational update, covering the activities of its forces on Tuesday, NATO reported no air strikes at all in Libya. Workers at Libyas Waha Oil Company demonstrated in Tripoli, meanwhile, demanding the resignation of boss Bashir al-Ashhab for alleged corruption and ties to the old regime, saying his refusal to quit was costing $36 million a day. Around 100 people gathered outside the prime ministers office holding placards and chanting Waha needs a change and Ashhab, take your chair and get out Waha is the countrys largest joint venture oil company, a partnership between the state-run National Oil Corporation and US firms ConocoPhillips, Hess and Marathon. It has a production capacity of more than 350,000 barrels per day but output has been suspended since late February. On the diplomatic front, British Foreign Secretary William Hague said on a visit to Algeria that Libyas neighbour should cooperate with the new regime over Gaddafi family members who took refuge there. His daughter Aisha fled to Algeria in late August with her brother Hannibal, their mother Safiya Gaddafis second wife and his eldest son Mohammed.
