The US State Department on Thursday said it could not confirm that deposed Libyan leader Muammar Gaddafi has been captured.
"We've seen the media reports but can't confirm them," State Department spokeswoman Beth Gosselin told Reuters.
White House officials were not immediately available to comment. The Pentagon also said it could not confirm the reports.
A senior official with Libya's National Transitional Council told Reuters that Gaddafi was captured near his hometown of Sirte at dawn as he tried to flee in a convory that came under attack from NATO warplanes.
The official also said the head of Gaddafi's armed forces, Abu Bakr Younus Jabr, was killed during the capture of the former Libyan leader.
