Charred skeletons of some 50 people were found in a makeshift prison next to a military base abandoned by elite troops loyal to Moammar Gadhafi in southern Tripoli on Saturday, an Agence France Presse reporter saw.

Local residents discovered the remains after rebel forces took control of the base of the 32 Brigade commanded by Gadhafi's son Khamis in the district of Salaheddin.

A convoy of six armored cars that could be carrying high Libyan officials, even fugitive leader Moammar Gadhafi, crossed from Libya into Algeria on Friday, the official Egyptian news agency reported quoting a Libyan rebel source.

The report could not immediately be confirmed from Algerian or Libyan sources.

Forces loyal to Libyan leader Moammar Gadhafi killed more than 150 prisoners in a "mass murder" as they fled the rebel takeover of Tripoli, a rebel military chief told Agence France Presse on Friday.

"There were instances of revenge in the last few hours before the fall of the regime," said Abdul Nagib Mlegta, head of operations for the takeover of the capital.

The African Union declined Friday to recognize Libya's rebel authority and instead called for the formation of an all-inclusive transitional government.

With rebels still battling diehard forces loyal to Moammar Gadhafi, South African President Jacob Zuma said at the end of an AU Peace and Security Council meeting in Addis Ababa that the rebels were not yet legitimate.

British warplanes bombed a bunker in Moammar Gadhafi’s birthplace of Sirte as rebel fighters prepared Friday to launch an offensive on the town, one of the last major regime holdouts east of Tripoli.

As insurgent leaders moved into Tripoli to begin a political transition, the African Union called for that process to be "inclusive."

Italy and France are not engaged in a colonial-style battle to seize Libya's riches, Italian Foreign Minister Franco Frattini said in an interview with Rai radio.

"There's not a race to arrive first in Libya," Frattini said, rejecting allegations in Italian newspapers of a competition between the two countries for the best contracts in a post-Gadhafi Libya.

Beneath the grassy courtyard of Moammar Gadhafi's private compound, long tunnels connect bunkers, command centers and spiral staircases that lead to a luxurious home filled with Gadhafi family photos.

The electric lights are out and the banks of telephones have gone dead.

The regime of Libyan leader Moammar Gadhafi killed Shiite cleric Moussa al-Sadr 33 years ago and threw his body into the sea, Iranian security sources said.

The sources, who had collaborated with the Shah’s regime, told an Iranian website that al-Sadr and his two companions Sheikh Mohammed Yacoub and journalist Abbas Badreddine were killed upon their abduction by the Gadhafi regime and their bodies were thrown into the sea after being attached to cement blocks.

U.S. Secretary of State Hillary Clinton on Thursday pledged support for a "new Libya," urging triumphant rebels to turn the page on Moammar Gadhafi's rule and build a secure, democratic state.

She also called on the rebels to guard weapons stockpiles and take a hard line against "extremism," as the United Nations began releasing $1.5 billion in Libyan assets earmarked for U.N. programs, food and basic services.

Embattled Libyan leader Moammar Gadhafi is either in southern Tripoli or has already fled to the desert, his defected former prime minister Abdessalam Jalloud said Thursday.

"He has only four people left around him. There are two possibilities: either he is hiding in the southern part of Tripoli or he left some time ago," Jalloud, who fled Tripoli and has been in Italy since Saturday, told a press conference.
