Gaddafi sons in conflicting offers
A man claiming to be Muammar Gaddafi's son Seif al-Islam is vowing to fight to the death and says nobody will surrender.
He also said he was speaking from the suburbs outside Tripoli and insisted his father is fine.
The defiant audio statement was broadcast on Al-Rai television station shortly after another statement by his brother, al-Saadi. Al-Saadi, offered a softer tone, saying he is ready to mediate talks with the rebels in order to stop the bloodshed.
