Ousted Libyan leader Muammar Gaddafi and his son Mo’tassim were buried yesterday in a secret desert location, a National Transitional Council (NTC) official said.

With their Western allies uneasy that Gaddafi was roughed up and shot after his capture last Thursday, NTC forces had put the body on show in a cold store while they argued over what to do with it, until its decay forced them to close the doors on Monday.

“Gaddafi and the son, Mo’tassim, were buried at dawn in a secret place with proper respects paid. We will release more details officially later,” a senior interim government official told Reuters.

A military official from the town of Misrata, where the corpses had been on public display in a meat locker, confirmed the burials.

The killing of the 69-year-old in his home town of Sirte ended eight months of war, finally ending a nervous two-month hiatus since the NTC’s motley forces overran the capital Tripoli.

But it also threatened to lay bare the regional and tribal rivalries that present the NTC with its biggest challenge.

NTC officials had said negotiations were going on with Gaddafi’s tribal kinsmen from Sirte and within the interim leadership over where and how to dispose of the bodies, and on what the Misrata leaders in possession of the corpses might receive in return for cooperation.

“No agreement was reached for his tribe to take him,” another NTC official told Reuters.

With the decay of the body forcing the NTC leadership’s hand, it appeared to have decided that an anonymous grave would at least ensure the plot did not become a shrine.

An NTC official had told Reuters several days ago that there would be only four witnesses to the burial, and all would swear on the Koran never to reveal the location.

NTC’s fears that Gaddafi’s sons might mount an insurgency have been largely allayed by the deaths of two of those who wielded the most power, military commander Khamis and Mo’tassim, the former National Security Adviser.

Mo’tassim was captured along with his father in Sirte and killed in similarly unclear circumstances and Khamis was killed in fighting earlier in the civil war.

An NTC official said Gaddafi’s long-time heir-apparent Saif al-Islam was in the remote southern desert and set to flee Libya, with the NTC powerless to stop him.

“He’s on the triangle of Niger and Algeria. He’s south of Ghat, the Ghat area. He was given a false Libyan passport from the area of Murzuq,” the official added.

He said Muammar Gaddafi’s former Intelligence Chief, Abdullah al-Senussi who, like Saif al-Islam, was wanted by the International Criminal Court.

“The region is very, very difficult to monitor and encircle. The region is a desert region and it has … many, many exit routes,” he said.

The death of the fallen strongman allowed the NTC to touch off mass rejoicing by declaring Libya’s long-awaited “liberation” last Sunday in Benghazi, the seat of the revolt.

But it also highlighted a lack of central control over disparate armed groups, and the jockeying for power among local commanders as negotiations begin in earnest to form an interim government that can run free elections.
