TRIPOLI (AFP) - No decision has been taken on when or where the body of Moamer Gaddafi will be buried, Libyas information minister said on Friday, amid lingering question marks over how the ousted despot met his end. No decision has been taken on the subject of Gaddafis burial, nor on whether his body would remain in Misrata where it was transported after he was fatally wounded after being captured in Sirte, Mahmud Shamam told AFP. NTC leaders have been cagey about plans for his burial, not wishing to see his grave become a rallying point for residual loyalists. At a news conference late on Thursday, hours after Gaddafis death was announced, the National Transitional Council (NTC) indicated that the former Libyan leader would be buried at an unknown location after an autopsy. Gaddafi was captured trying to flee Sirte, his hometown, as NTC fighters raced through to mop up the last pockets of loyalist resistance, and subsequently died of his wounds in circumstances that remain hazy. NTC leaders claim he was shot in the head when he was caught in crossfire between his supporters and new regime fighters soon after his capture at a sewage culvert where he had taken refuge. Gaddafis body was laid out overnight in a private residence in Misrata Libyas third-largest city, which his forces devastated in a protracted siege that proved to be one of the turning points of the eight-month uprising. Meanwhile, the circumstances surrounding the death of Libyas ousted despot Moamer Gaddafi are unclear and an investigation is needed, the UN human rights chief said Friday. On the issue of Gaddafis death yesterday, the circumstances are still unclear, Navi Pillays spokesman Rupert Colville said in Geneva. There are four or five different versions of how he died. There should be some kind of investigation given what we saw yesterday. Question marks remained about how Gaddafi met his end. Mobile phone footage appeared to show him captured bloodied but still alive and then killed by his captors. The two videos ... taken together are very disturbing, noted Colville. Nevertheless, Gaddafis death and the fall of Sirte has led to a new era for Libya, he said. A new era is now beginning which should respond to the aspirations of the people for democracy and human rights, said Colville, calling for human rights to be a cornerstone for all future policies and actions in the country. One key aspect to obtain closure on the legacy of Gaddafi ... would be to ensure that justice is done, the spokesman added. The thousands of victims who suffered loss of lives, disappearances, torture and other serious human rights violations since the conflict occurred in February 2011 as well of those who suffered human rights violations throughout Gaddafis long rule have the right to know the truth. And they have the right to see the culture of impunity brought to an end and to receive reparations, he added.
