The last top figures of his ousted regime, Gaddafi's son Seif al-Islam and former intelligence chief Abdullah al-Senussi, meanwhile, were poised to cross the border into Niger, a Tuareg official said.
Seif al-Islam was "near the Niger border, he hasn't entered Niger yet but he's close," a local official from the northern Niger Agadez region told AFP on condition of anonymity.
A Misrata military council member, also without being named, said that Gaddafi was buried yesterday night in a religious ceremony, along with another of his sons, Mutassim, and former defence minister Abu Bakr Yunis Jaber.
The bodies had been put on display in a market freezer on the outskirts of Misrata, a city 215 kilometres east of Tripoli, with thousands of Libyans queuing up since Friday to view and photograph them.
In Benghazi, a senior official of the National Transitional Council said the burial "took some time" to organise due to a "disconnect between the local (Misrata) council and the NTC."
According to guards at the entrance to the market, a convoy of four or five military vehicles took the bodies away to an unknown location, being kept secret to avoid the site turning into a rallying point for Gaddafi supporters.
