The International Criminal Court (ICC) said it had held talks - through intermediaries - with Saif al-Islam about his possible surrender.

Prosecutors stressed that Gaddafi's son, who is wanted for crimes against humanity, would get a fair trial.

Saif al-Islam, who was once the presumed successor to his father, has been in hiding for months.

Recent reports claimed he was in a convoy heading toward Libya's desert border with Niger, where other Gaddafi allies have fled.

But those reports have not been confirmed, and the ICC said it did not know where he was.
