A 1million bounty was placed on the head of Colonel Gaddafi yesterday as rebel leaders offered an amnesty to any member of his regime who captures or kills him. With still no sign of where the ousted tyrant is hiding, an unnamed businessman posted the reward to anyone handing him over 'dead or alive. It was supported by rebel chief Mustafa Abdel Jalil, head of the National Transitional Council (NTC), in a clear indication that the insurgents have no idea where the 69-year-old Gaddafi is. The need to find him was given added urgency yesterday by suggestions that the regime could still have a stockpile of chemical weapons thought to be mustard gas hidden in the desert. Fierce fighting continued in Tripoli yesterday with the death toll since Sunday passing 450 with another 2,250 wounded. Snipers on rooftops and hidden in buildings were still picking off rebels and civilians including women and children. Battles raged around Gaddafis vast Bab al-Aziziya compound, which rebels had stormed 24 hours earlier. One British doctor in Tripoli said he spent Tuesday at the field hospital in the compound. He told the BBC there were 'lots of wounded and many dead. They couldnt get them out so there were literally bodies piled up in the corner. The rebel fighters are now using Bab al-Aziziya as a staging area for their operations despite coming under fire from rifles and rocket propelled grenades. Rebels claimed to be in control of 95 per cent of Libya and 90 per cent of Tripoli and declared Gaddafis rule effectively over. Abdul Ati al-Obeidi, Gaddafis former foreign minister, said the regime had come to an end and rebels were now responsible for restoring law and order to Libya. There were calls for oil workers to return to work at two key refineries under rebel control so production can being again 'within days. U.K Prime Minister David Cameron will travel to Paris next week to meet rebel leaders. The UK Prime Minister and the French President Nicolas Sarkozy issued a joint invitation to Mr Jalil. MI6 is said to be using its contacts and agents on the ground to try to find Gaddafi while the eavesdropping centre at GCHQ will be trying to intercept any communications, with technology matching his voice to any calls made from satellite telephones. Nato, which is employing its surveillance planes to spot any signs of escape across the desert and has Special Forces on the ground, is desperate to prevent a repeat of Iraq after the fall of Baghdad, when Saddam Hussein was on the run for eight months. Foreign Secretary William Hague, who chaired a meeting of the National Security Council in London, admitted there was no news where Gaddafi was hiding and called on the Libyan dictator to recognise his rule was over and stand down his forces. 'There is a clear, fundamental decisive rejection of the regime by the people of Libya, he said. 'It is time now for Colonel Gaddafi to stop issuing delusional statements and recognise that control of the country is not going to return. The renewed fighting erupted hours after Gaddafi, who has ruled Libya with an iron fist for 42 years, vowed to fight on 'until victory or martyrdom and called on Tripolis residents to free the city from the 'devils and traitors who have overrun it. In a broadcast given from an unknown location, the ousted despot asked: 'Why are you letting them wreak havoc? Sounding subdued and without his usually fiery rhetoric, he said he would fight 'the aggression with all strength until either victory or death. Much of the latest fighting was centred in the neighbourhood of Abu Salim, adjacent to the Gaddafi compound and home to a notorious prison. The district is one of the last remaining regime strongholds within the capital and rebels were again assisted by Nato airstrikes blitzing the area, huge explosions sending plumes of black smoke spiralling above the city. Fierce fighting also raged in the area of the Rixos Hotel, close to the seized compound, where 35 journalists effectively held hostage by the regime since rebels stormed the city were finally released.
