Overcome with grief, rebels fighters on Saturday buried the man who had led them for the past 5 months in a revolt against Muammer Gaddafi.A coffin carrying Abdel Fattah Younes was carried through Benghazi as supporters mourned his loss.The circumstances surrounding his death are unclear.Rebel officials said Younes was killed by fellow rebel fighters and that an investigation is pending."...Who imprisoned him. All these details - this is what the committee will investigate. The committee have a very short timeline to give us answers to all these questions...Younes' death has undoubtedly hampered the rebels spirits... although along the front lines near Zlitan (zleee-tah), they do their best to carry on," Libyan rebel Oil and Finance Minister Ali Tarhouni said."Our martyr, the major-general Abdul-Fattah Younes, is like any other person who is fighting on the frontline. Of course, we were sad to hear of his death, but we hope it will be an extra motive for us in the fight against the tyrant. We count him as a martyr," rebel fighter Khaled al-Uwayyib said.Some critics say Younes' death signals growing factions amongst rebel ideologies.
