The burial of slain leader Moammar Gaddafi has been delayed until the circumstances of his death can be further examined and a decision is made about where to bury the body, Libyan officials said Friday, as the UN human rights office called for an investigation into his death. The transitional leadership had said it would bury the dictator Friday in accordance with Islamic tradition. Bloody images of Gaddafi's last moments in the hands of angry captors have raised questions over his treatment minutes before his death. One son, Muatassim, was also killed but the fate of Gaddafi's one-time heir apparent Saif Al-Islam was unclear. Justice Minister Mohammed Al-Alagi said Saif Al-Islam was wounded and being held in a hospital in the city of Zlitan. But Information Minister Mahmoud Shammam Friday that the son's whereabouts were uncertain. Shammam said Gaddafi's body was still in Misrata, where it was taken after he was found in his hometown of Sirte, and revolutionary forces were discussing where it should be interred. Thursday's death of Gaddafi, two months after he was driven from power and into hiding, decisively buries the nearly 42-year regime that had turned the oil-rich country into an international pariah and his own personal fiefdom. It also thrusts Libya into a new age in which its transitional leaders must overcome deep divisions and rebuild nearly all its institutions from scratch to achieve dreams of democracy. Many Libyans awoke after a night of jubilant celebration and celebratory gunfire with hope for the future but also concern that their new rulers might repeat the mistakes of the past. Khaled Almslaty, a 42-year-old clothing vendor in Tripoli, said he wished Gadhafi had been captured alive. “But I believe he got what he deserved because if we prosecuted him for the smallest of his crimes, he would be punished by death,” he said. “Now we hope the NTC will accelerate the formation of a new government and ... won't waste time on irrelevant conflicts and competing for authority and positions.”
