Libyan rebels have announced an amnesty for anyone within Col Muammar Gaddafi's inner circle who captures or kills him. They have also announced a reward of 1.7m dollars for capturing Gaddafi.However, Col Gaddafi's whereabouts are unknown, though rebels have said they think he is still in or around Tripoli. Rebels fighters have fought running battles in the capital, where pockets of pro-Gaddafi resistance remain. The fugitive leader has vowed in an audio message to fight until victory or martyrdom. His sprawling Bab al-Aziziya compound was overrun on Tuesday, though firefights within the complex have continued. Col Gaddafi's forces are still firmly in control of the strategic coastal city of Sirte – as well as several key bases in southern Libya.
