Muammar Gaddafi's fugitive son Saif al-Islam and former intelligence chief Abdullah al-Senussi are proposing to hand themselves into the International Criminal Court in The Hague, a senior Libyan military official with the National Transitional Council said on Wednesday.

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

Saif al-Islam is wanted by the war crimes court, as was his late father. There is also a warrant out for Senussi.

Saif 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.

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.

They had concluded that it was not safe for them to remain in Libya, to go to Algeria, or to cross into Niger, where one of Gaddafi's sons is already sheltering. Other family members are in Algeria.

They feel that it is not safe for them to stay where they are or to go anywhere, Mlegta said.

In any case, Niger was asking for too much money for them to stay.
