Gaddafi vows fight as world backs new leaders; Rebels extend surrender deadline 1 week

"Let it be a long battle. We will fight from place to place, from town to town, from valley to valley, from mountain to mountain," Gaddafi said in a message relayed by satellite TV on the anniversary of the coup that brought him to power in 1969.

"If Libya goes up in flames, who will be able to govern it? Let it burn," he said with his trademark verbal flamboyance.

In further comments broadcast later, he vowed to prevent oil exports, in the kind of threat that stirs fears of an Iraq-style insurgency: "You will not be able to pump oil for the sake of your own people. We will not allow this to happen," Gaddafi said. "Be ready for a war of gangs and urban warfare."

Amid conflicting reports of where the 69-year-old fugitive might be, a commander in the forces of the new ruling council said he had fled to a desert town south of the capital, one of several tribal bastions still holding out.

Seeking to avoid more bloodshed, opposition forces also extended by a week a deadline for Gaddafi's hometown of Sirte, on the coast, to surrender.
