TRIPOLI (AFP/Reuters) - British warplanes have bombed a bunker in Moamer Gaddafis hometown of Sirte, as rebel fighters grouped on Friday for another push on one of the last major regime holdouts east of Tripoli. As insurgent leaders moved into Tripoli to begin a political transition, the African Union called for that process to be inclusive, while the UN human rights chief warned against assassinating strongman Moamer Gaddafi , whose whereabouts is unknown and who has a $1.7 million rebel price on his head. At around midnight, a formation of Tornado GR4s fired a salvo of Storm Shadow precision-guided missiles against a large headquarters bunker in Gaddafis home town of Sirte, the defence ministry said in London. Speculation that Gaddafi might have found refuge in the town, which lies 360 kilometres east of Tripoli, has not been confirmed. NATO said on Friday that its planes had hit 29 armed vehicles and a command and control node in the vicinity of Sirte. Forces loyal to fugitive Libyan strongman Gaddafi on Friday bombarded the capitals airport on Friday, damaging a plane, Dubai-based Al Arabiya TV reported. There was an exchange of gunfire between Gaddafi forces and rebel fighters near the airport, the channel said in a rolling banner headline. Libyan rebels had stormed Tripolis Abu Salim district, one of the main holdouts of forces loyal to Gaddafi in the capital, after NATO air strikes on a building in the area on Thursday. Rebels and forces loyal to Gaddafi battled at Ras Jdir on Libyas coastal border with Tunisia, Arab satellite television Al Jazeera reported on Friday. The Libyan rebel political leader said on Friday the transitional government-in-waiting will seek a seat at the United Nations next month following the apparent overthrow of Muammar Gaddafi this week. We hope that next month Libya will be occupying the seat it holds at the United Nations, Mahmoud Jibril told a news conference in Istanbul. On Thursday, the National Transitional Council (NTC) moved many of its top people from their Benghazi base, just days after rebel fighters overran Tripoli, going on to capture Gaddafis headquarters and vast swathes of the capital. Ali Tarhuni, a NTC official, said their leader, Mustafa Abdel Jalil, would arrive as soon as the security situation permitted. I declare the beginning and assumption of the executive committees work in Tripoli, Tarhuni, the executive committees vice chairman and minister of oil and economics, said in the capital. Long live democratic and constitutional Libya and glory to our martyrs, he said, announcing the holders of key posts in a new provisional government. He called on forces loyal to Gaddafi to lay down their arms, and promised they would be treated lawfully. In Geneva, the UN human rights chief warned against bounty hunters who may be seeking to kill Gaddafi , saying assassinations are not within the rule of law. That applies to Gaddafi as well as everybody else, said spokesman Rupert Colville in a response to a question about the reward for Gaddafi , dead or alive. Colville said the best solution would be to capture Gaddafi alive and follow through on an International Criminal Court (ICC) arrest warrant for crimes against humanity. In that vein, a senior African Union official said that with the conflict about to end, the body should support efforts for an inclusive transition in Libya. On Thursday, US Secretary of State Hillary Clinton called on the rebels to guard weapons stockpiles and take a hard line against extremism. There can be no place in the new Libya for revenge attacks and reprisals ... Libyas future will be peaceful only if the leaders and people of Libya reach out to each other in a spirit of peace. She pledged support for the new Libya, urging the triumphant rebels to turn the page on Gaddafis rule and build a secure, democratic state. Amid all these concerns, Amnesty International claimed that abuses were being committed on both sides, reporting that a jailed boy had been raped by Gaddafi guards and that rebels were mistreating African migrant workers accused of being mercenaries. The whereabouts of Gaddafi remain unknown despite an intensive search by rebel forces, and on Thursday he broadcast a new audio message calling on the populace to take up arms. As the rebels worked to consolidate their gains politically, there were still desperately in need of funding. NTC number two Mahmud Jibril said in Istanbul Friday that it was essential that the West release all of Libyas frozen assets. Salaries of civil servants need to be paid. The life needs to continue on its normal course, Jibril said, a day after senior diplomats of the Libya Contact Group met in Istanbul and agreed to speed up release of some $2.5 billion in frozen Libyan assets by the middle of next week. At the same time, the UN Security Council released $1.5 billion of seized Libyan assets to be used for emergency aid. The money will be moving within days, a US diplomat said. Washington said Thursday the money would pay for UN programmes, energy bills, health, education and food, and would not be used for any military purposes. Italian Foreign Minister Franco Frattini said Rome would next week release $504 million frozen in Italian banks.
