Tripoli, Sep 2 (IANS): Libyan leader Muammar Gaddafi has once again vowed in an audio message broadcast on television that he would not surrender. He urged his loyalists to continue their resistance to the rebellion.

"We are not weak women. We are not slaves. We can not give up. We can not surrender," Gaddafi said in the message broadcast on Syria's Al-Rrai TV channel.

"Let this be a long fight and let Libya be engulfed in flames," he said.

Gaddafi called on his supporters in the capital Tripoli to fight back and "set ambushes" against the "collaborators" of NATO.

He also urged the tribes who support him to continue fighting even if they could not hear from him again.

"All Libyan tribes are heavily armed and cannot be brought to their knees. We'll be awarded victory ultimately. We can never surrender," said Gaddafi, whose whereabouts remain unknown.

In an audio message broadcast on the Syrian TV channel Wednesday, Gaddafi's second son, Saif al-Islam said his father was doing well and vowed to "liberate" the Green Square in Tripoli from the rebels' control.
