TRIPOLI (AFP/Reuters) - Moamer Gaddafi accused the West on Wednesday of wanting to seize Libyas oil and warned a no-fly zone would backfire as his forces pounded rebel lines and a top aide jetted into Cairo. The colonialist countries are hatching a plot to humiliate the Libyan people, reduce them to slavery and control the oil, Gaddafi said on state television. He again accused Al-Qaeda of being behind the insurrection that began on February 15 and called on inhabitants of Benghazi, the rebels main base, to liberate the eastern city. Libyas government offered a $410,000 bounty for the capture of Mustafa Abdel Jalil, head of the rebel national council which declared itself the North African countrys sole representative in Benghazi on Saturday. In a separate television interview with Turkeys public TRT channel, Gaddafi said, paradoxically, he was in favour of a move by the West to impose a no-fly zone over Libya to prevent his forces from attacking rebels from the air. A mechanic said a pipeline had been blown up, while an opposition spokesman said air raids had struck several oil installations. Several members of Libyan leader Muammar Gaddafis forces, including a general and a colonel, were killed in fighting in the western town of Zawiyah on Wednesday, Al Jazeera satellite channel reported Scores of rebels packed into dozens of vehicles and retreated into Ras Lanuf after several hours of sustained shelling and at least three air strikes west of the town. Fighting in eastern Libya has killed at least 400 people and wounded 2,000 since February 17, medics said. There have been 400 dead since the beginning in Derna, Baida, Brega, Benghazi, Ras Lanuf and Bin Jawad, Salah Jabar, a medical co-ordinator for cities held by the rebels in the east, told reporters in Benghazi. In Zawiyah, just west of Tripoli, the battle for control of the strategic oil city was undecided. The revolutionaries control the centre of Zawiyah and Gaddafis forces are surrounding it. Its 50-50, a long-term Moroccan resident said after crossing the border into Tunisia. A fighter told Reuters pro-Gaddafi forces had entered the main square as rebels pulled back. A local doctor confirmed the report and said the death toll in the days fighting was at least 40 and probably many more. Meanwhile, a member of Gaddafis inner circle, Abdelrahman al-Zawi, landed in Cairo aboard a private Libyan plane, an airport official told AFP. Meanwhile, Libyan officials who landed in Cairo earlier on Wednesday were carrying a letter from embattled leader Moamer Gaddafi for the Arab League, Italian Foreign Minister Franco Frattini said. The plane from Tripoli was carrying a Libyan army general and probably the defence minister... bringing Egypts transition government a letter from Gaddafi stating his intention to meet with the Arab League, he said.
