Gaddafi in new 'fight on' plea

In a new audio message from hiding, Muammar Gaddafi is calling on his followers to rise up and fight, saying “this is the zero hour”.

Fighters from the revolutionary forces that drove him from power last month have begun an assault on one of his last areas of support in the town of Bani Walid, south-east of the capital.

Gaddafi’s latest message was broadcast repeatedly on the town’s radio station on Saturday night.

In it, he urges supporters to fight and says those who do not will go to hell.
