Muammar Gaddafi's son Saadi is attempting to negotiate his own surrender, reports suggest.
The military leader of Libya's interim government, Abdel Hakim Belhaj, told the Associated Press that Saadi called him on Tuesday to see if his safety could be guaranteed. Belhaj said Gaddafi's son was told he would be treated within the law.
He added that Saadi called again on Wednesday, but he did not speak to him.
Belhaj made similar claims on Wednesday morning to Al Jazeera.
It also emerged on Wednesday that officials from the EU are likely to remove restrictions on Libyan ports and companies at Thursday's Friends of Libya summit in Paris, in a sign trade with the country could be re-initiated.
The European Commission was confident the facilities would be under the control of the new Libyan authorities, reported The Guardian.
China said it would be sending its vice foreign minister, Zhai Jun, to observe the meeting.
China and Russia have not yet recognised the Libyan interim National Transitional Council as the country's legitimate government.
France has also asked the UN Security Council's sanctions committee to allow Libyan assets in French banks to be released to the NTC.
Attacks continued outside Sirte on Wednesday as anti-Gaddafi forces continued to search for the deposed leader.
Meanwhile in Tripoli, Amnesty International has said that black Libyans and sub-Saharan Africans are at risk of abuse by anti-Gaddafi forces.
An Amnesty delegation reportedly saw three opposition fighters in civilian clothes dragging a black patient from his bed in the Central Tripoli Hospital before detaining him.
“Amnesty International witnessed one man being hit and one dragged out of his hospital bed to an unknown fate,” said Claudio Cordone, Senior Director at Amnesty International.
“We have to fear for what may be happening to detainees out of the sight of independent observers."
Concerns have previously been raised over the welfare of migrants in the country because of possible revenge attacks on people believed to have been mercenaries. The African Union said earlier this week that rebels may be indiscriminately killing black people because they have confused innocent migrant workers with mercenaries.
In the UK the NTC spokesman Guma el Gamatay said that the first of the released Libyan assets have begun to reach Benghazi.
