The leader of the Libyan opposition has gathered rebel commanders to honour the 70th anniversary of the founding of the country's armed forces, in a display of unity aimed at restoring stability to his administration.<br /><br />The ceremony came on the same day that Mustafa Abdel Jalil, the chairman of the National Transitional Council (NTC), sacked his entire cabinet for mishandling the aftermath of a high-profile assassination. <br /><br />Abdel Fattah Younes, the rebels' overall military commander, was killed late last month in murky circumstances after being summoned to Benghazi by the NTC, and his case remains unexplained.<br /><br />Jalil and other opposition supporters are hoping that the cabinet shakeup, and a crackdown on independent armed groups operating in rebel territory, will help assuage local and international concern.<br /><br />Al Jazeera's Tony Birtley reports from Benghazi.
