Muammar Gaddafi's son Saadi has blamed his high-profile brother for the collapse of talks with Libya's new rulers

Muammar Gaddafi's son Saadi has blamed his high-profile brother for the collapse of talks with Libya's new rulers, CNN television reported late on Sunday.

Saadi Gaddafi told CNN in a telephone interview that an "aggressive" speech broadcast by his brother, Saif al-Islam Gaddafi, a few days ago had led to the breakdown in negotiations, paving the way for an attack.

The town southeast of Tripoli is one of the last strongholds of pro-Gaddafi fighters where at least one of the ousted despot's sons is thought to be hiding.
