In a statement to the UN Security Council on November 2, Luis Moreno-Ocampo called on other countries to disrupt such plans.

The court has been trying to negotiate the surrender of the 39-year-old, who is wanted for war crimes.

Mr Ocampo also said they were examining allegations against NATO and interim forces, as well as pro-Gaddafi troops.

He said they would examine alleged crimes by all sides "impartially and independently".  

Saif al-Islam, who was once the presumed successor to the former Libyan leader, has been in hiding for months.

The court has been holding talks with intermediaries to secure his arrest, following the death of his father on 20 October.
