Moammar Gadhafi's body was buried overnight in a secret location, a Libyan military council member said Tuesday.

Four or five military vehicles took away the bodies of Gadhafi, his son Muatassim and former Defense Minister Abu Bakr Younis late Monday night to an unknown location. Three religious leaders loyal to Gadhafi performed a ceremony before the burial.

Gadhafi's family wanted the bodies buried outside the former leader's hometown of Sirte. National Transitional Council leaders had expressed a preference for a secret burial. Determined to prevent Gadhafi's grave becoming a shrine for his supporters, the NTC wanted its location kept secret, refusing custody to his tribe, many of whom live in Sirte.

Questions have been raised over the former leader's death after a video showed him being alive at the time of capture. Officials said he had been killed subsequently in crossfire. A postmortem examination carried out on the 69-year-old's body Sunday showed that he had received a bullet wound to the head, medical sources said.

Acting Libyan leader Mustafa Abdul Jalil said the NTC had formed a committee to investigate the circumstances surrounding his death. Meanwhile, the bodies of soldiers who had been loyal to Gadhafi were being buried in Misrata.
