Tripoli: The burial of slain leader Muammar 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 today, 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 Seif al-Islam was unclear.

Justice Minister Mohammed al-Alagi said Seif al-Islam was wounded and being held in a hospital in the city of Zlitan.

But Information Minister Mahmoud Shammam said on 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.

Gaddafi body stashed in shopping center freezer

Muammar Gaddafi's blood-streaked body was stashed in a commercial freezer at a shopping center on Friday as Libyans tried to keep it out of the public eye and away from crowds as they figure out where and when to bury the hated leader.

An AP correspondent saw the body at the shopping center in the coastal city of Misrata, home of the fighters who killed the ousted leader a day earlier in his hometown of Sirte.

The body, stripped to the waist and wearing beige trousers, was laid on a bloodied mattress on the floor of an emptied-out room-sized freezer where restaurants and stores in the center normally keep perishables.

A bullet hole was visible on the left side of his head, with the bullet still lodged in his head, according to the presiding doctor, and in the center of his chest and stomach. His hair was matted and dried blood streaks his arms and head.

Outside the shopping center, hundreds of civilians from Misrata jostled to get inside for a peek at the body, shouting "God is great" and "We want to see the dog."

The makeshift provisions for the corpse, at one point it was kept in a private house on Thursday, reflected the disorganisation and confusion that has surrounded Gaddafi's death.

Gaddafi was alive when captured

Muammar Gaddafi was alive when he was captured by the National Transitional Council fighters in his hometown Sirte shows a video on YouTube.

The video appears to show Gaddafi moments after his arrest, said It seems to capture the final moments of the man who ruled Libya for 42 years, after coming to power in a bloodless coup in 1969.

The video is shaky and shows fighters crowding around a bloodied Gaddafi.

There is now an internet debate on whether Gaddafi died from his wounds or was he killed after his capture.

Gunshots can be heard in the video as the camera moves away from the dictator.

The fall of Sirte and Gaddafi's death brought an end to a tumultuous period in Libya, which witnessed an uprising that was inspired by the Egyptian and Tunisian revolt.

Misurata fighters display Gaddafi's war trophies

Dramatic new mobile footage has surfaced showing that Libyan despot was captured bloodied but still alive and then killed by his captors, who then scrambled for trophies from the dead body.

The new footage has prompted the UN human rights chief to ask for an international investigation into the circumstances surrounding the death of Libya's ousted despot, US media reports said.

A UN human rights spokesman has described the mobile videos as very disturbing.

New York Times said a small group of fighters from the port city of Misurata were at the vanguard of the force attacking Gaddafi's final hideout, stumbling upon him, hiding in a drainage pipe.

Giving the first hand account of the dictator's last moments, the NYT quoted the two fighters, 21-year-old Omran Shaaban, and his unnamed friend, who claimed that they were the first to confront the dictator lying injured in the pipe.

"When he saw us" he said in his trademark indignation "what's happening?" They said he was bleeding from his head and chest, but he was well enough to speak.

Without clarifying how Gaddafi was killed, Shaaban displayed in his hometown Misurata the trophies of the revolution.

They included Gaddafi's 'golden gun', his 'satellite phone', his 'brown scarf' and one 'black boot'.

NYT said, amid the other souvenirs of war, the biggest prize was Gaddafi's body which was shuttled around Misurata, the whole of last night.

Interpol, ICC urge Gaddafi son to give up

The World police body Interpol and the International Criminal Court (ICC) today urged Seif al-Islam, the most prominent son of Muammar Gaddafi, to give himself up and "face justice".

In a statement, the two institutions "urged the former Libyan leader's son Seif to give himself up and for the national authorities of the country where he is hiding to guarantee and facilitate his safe transfer to The Netherlands to face justice."

"Following my discussions with (ICC) Prosecutor (Luis) Moreno-Ocampo, we agree that it is in the best interests of Seif Al-Islam Gaddafi as well as in the interests of justice that he surrender himself as swiftly as possible and face the charges levelled against him," Interpol Secretary General Ronald Noble said in the statement.

"Colonel Gaddafi will not be able to answer to the crimes levelled against him which makes it even more important that those who were part of his inner circle and who remain at large are captured and face their accusers so that the rule of law can run its course."

Interpol issued a "red notice" in September for the arrest of Gaddafi, who was killed today, Seif al-Islam and the former regime's intelligence chief Abdullah al-Senussi.

In June, ICC judges issued arrest warrants against the three for "crimes against humanity" by troops under their orders, using "lethal force" to quell the uprising against his regime.
