One of former Libyan leader Moammar Gadhafi's sons told a Syrian television station late Wednesday that he is in the suburbs outside Tripoli and that his father “is fine.”

Seif al-Islam Gadhafi vowed that he and other family members will fight until death and said nobody will surrender. He told the pro-Gadhafi al-Rai television station that morale among loyalist fighters is high.

The defiant audio statement was broadcast shortly after another comment by his brother, al-Saadi, who said he is ready to mediate talks with anti-Gadhafi forces in order to stop the bloodshed.
