New York: Fugitive Libyan leader Col Muammar Gaddafi is ready to begin talks to transfer power, US media has been told.

The spokesman told the Associated Press news agency negotiations would be led by Col Gaddafi's son, Saadi. He also said Col Gaddafi was still in Libya.

The Associated Press news agency in New York reported that it had received a call from Col Gaddafi's spokesman Moussa Ibrahim, who said the former leader was still in Libya although he did not specify where.

Mr Ibrahim, whom AP says it identified by his voice, said Col Gaddafi had offered power transfer negotiations headed by his son, Saadi.

Early this week, CNN reported it had been in email contact with Saadi Gaddafi who confirmed his desire to negotiate a ceasefire.

"I will try to save my city Tripoli and 2 millions of people living there... otherwise Tripoli will be lost forever like Somalia," he wrote.

Without a cease-fire, Mr Gaddafi added, "Soon it will be a sea of blood."

Rebels say desperately-needed fuel and water supplies should begin arriving in Tripoli on Sunday. Meanwhile, more than 50 charred bodies have been found in a burnt-out warehouse south of Tripoli.

Residents of the district of Salah al-Din said they were civilians who had been executed on Tuesday by members of a brigade commanded by Col Gaddafi's son, Khamis, before they abandoned a nearby military base.

Human Rights Watch says it has evidence that pro-Gaddafi forces killed at least 17 prisoners and carried out "suspected arbitrary executions of dozens of civilians, including professionals" in the days before Tripoli fell to the rebels.

On Friday, more than 200 decomposing bodies were found at an abandoned hospital in the capital's Abu Salim district. Doctors and nurses fled because of the fighting and many injured patients were left to die.
