SIRTE (AFP) - Anti-Gaddafi fighters Monday overran the ousted strongmans birthplace of Qasr Abu Hadi, medics said, marking a symbolic victory in their battle to eradicate the last vestiges of his 42-year rule. The battlefield success came as Libyas new rulers announced a shakeup of their executive, which is overseeing the countrys transition until an interim government is formed once Gaddafis remaining bastions of support are subdued. Abu Hadi is completely free (of loyalist fighters), said Dr Taha Sultan at a field hospital on the eastern outskirts of the Mediterranean city of Sirte. Our medical team came through the village and they tell us it is free, Sultan told AFP. The capture of Qasr Abu Hadi, where Muammer Gaddafi was reportedly born in a nomad tent in 1942 when it was still a tiny desert hamlet, is the latest in a string of loyalist communities to be mopped up by National Transitional Council troops as they close in on the toppled despots diehard fighters inside Sirte. Sultan was unable to say whether there were casualties in the fight for Qasr Abu Hadi, but he said two NTC fighters were killed in front line fighting in another part of eastern Sirte on Monday, and six were wounded. Qasr Abu Hadi prospered under the rule of its most famous son and the surrounding countryside is dotted with large villas in gated compounds. Most were empty, their occupants fled. But some housed large numbers of families huddled together for safety amid evident fear of retribution from the victorious NTC forces. Most residents refused to speak to AFP and those who did were clearly afraid. We are caught in the crossfire. Gaddafis men hide in our farms and rebels fire shells from the other side, one man told AFP, declining to give his name. Two days ago, five members of a family in a house next to mine were killed when a rocket struck it. We dont know who fired that rocket, said the man, dressed in a traditional dishdasha. He said he had 30 families hiding in his large villa but would not allow AFP in. They all are scared. There are many children too with them and they have no milk or food. I only have bread and tea to offer to them. NTC fighters said some of the villas had been used as arms caches by Gaddafi loyalists. An International Committee of the Red Cross team tried to deliver desperately needed medical supplies to the Ibn Sina hospital in the centre of Sirte but was forced to turn back when a firefight erupted on the front line to the west, preventing it from crossing over. NTC commanders, who came in for strong criticism when they launched an attack on Gaddafi forces in a nearby conference centre while the ICRC was making a delivery to the same hospital on Saturday, insisted they were only returning fire. We didnt launch an attack. We were returning fire, the NTC operations commander said, adding that the NTC troops had come under intense bombardment from Gaddafi forces using rocket-propelled grenades and 107mm rockets. The hospitals are full of armed individuals, there are also operations rooms inside because they know we wont hit the hospitals, Muttawa told AFP. They fire from the hospitals, from the university. They dont stick to any code of conduct. We will. The ICRC team was trying to deliver two truckloads of medical supplies, including oxygen and hygiene kits, as well as nappies, rice, pasta, cooking oil and tinned tomatoes. Hundreds of Sirte residents have been fleeing in packed vehicles, with some sitting on top of possessions piled high in the rear of pick-ups. On the political front, the NTC announced minor changes to the line-up of its executive, at a news conference in the eastern city of Benghazi. NTC chief Mustafa Abdel Jalil told reporters the post of deputy head of the executive, until now held by Ali Essawy, was being scrapped while Ahmed Kissa was named to head the new post of minister for Libyans killed or wounded. Hamza Abu Fas was to replace Salem al-Sheiky as minister of Islamic affairs, he added. Abdel Jalil said the current head of the executive, Mahmud Jibril, would retain his position as well as the post of foreign minister. We appeal to the Libyan people to be patient because the hour of liberation is near, Abdel Jalil said. The NTC, which has been ruling Libya since Gaddafi was toppled in a revolt in August, has postponed forming a transitional government until the last bastions of support for the strongman are overrun. In Brussels, NATOs chief called on the new Libyan regime to secure stockpiles of weapons amassed by Gaddafi that could fall into the wrong hands. Secretary General Anders Fogh Rasmussen refused to confirm reports that thousands of surface-to-air missiles were on the loose in Libya, but said it was up to the NTC to keep weapons secured. In general, all weapons that end up in the hands of people with bad intentions is a big problem, he told a news conference ahead of a meeting of NATO defence ministers on Wednesday and Thursday.
