Seif al-Islam, formerly known as the heir-apparent of his father, Libyan dictator Muammar Gaddafi, has offered the Libyan rebels' government to turn himself in, according to a Transitional National Council official.

Gaddafi's fugitive son Seif al-Islam and former intelligence chief Abdullah al-Senussi managed to escape at the end of last week, when the rebels captured and killed the former dictator himself after overwhelming the regime loyalists at Sirte.

Seif al-Islam and al-Senussi are now proposing to hand themselves into the International Criminal Court in The Hague, according to the report cited by Al Jazeera.

"They are proposing a way to hand themselves over to The Hague," Abdel Majid Mlegta told Reuters from Libya.

Both men have arrest warrants on war crimes charges by the International Criminal Court (ICC), together with the deceased dictator.

Mlegta said his information came from intelligence sources who told him that Saif al-Islam and Senussi were trying to broker a deal to surrender to the court through a neighbouring country, which he did not name.

Seif al-Islam has been on the run since Libyan forces overran his father's home town of Sirte at the weekend. He is thought to be somewhere near Libya's southern border with Niger.

After escaping from Sirte, Seif al-Islam reportedly vowed to keep fighting the TNC, and to avenge the murder of his father.
