The International Criminal Court in The Hague said Tuesday it had never received official confirmation from the Libyan rebels that Saif al-Islam Gadhafi had been captured.

Saif's arrest had been claimed by the rebels Sunday night, but he appeared before foreign media in Tripoli early Tuesday, raising questions as to the rebels' credibility.

There was no official confirmation from the National Transitional Council, ICC official Fadi el-Abdallah said. Different answers were given. That was a little ambiguous.

He added that statements from both the ICC and the prosecutor on Monday said they had received information about the arrest but that they were trying to confirm it.

The office of the prosecutor, which told Reuters early Monday it had confirmation from sources that Saif had been arrested, has not yet responded to requests for comment.
