Col Muammar Gaddafi still a big problem to the world

Col Muammar Gaddafi still poses a danger for Libya and the world, the head of the Libyan rebels has said.

National Transitional Council (NTC) head Mustafa Abdul Jalil said Nato and other allies must continue supporting rebels against the "tyrant".

The rebels have taken the small town of Nofilia on their way to the Gaddafi stronghold - and hometown - of Sirte.

Col Gaddafi's whereabouts remain unknown since rebels swept into Tripoli last week, capturing his compound.

They already control most of Libya, after months of clashes since the first protests began.
