Libya conflict: Hundreds of residents flee Sirte

Streams of civilians have been fleeing the Libyan city of Sirte, ousted leader Muammar Gaddafi's birthplace.

Travelling in vehicles packed with belongings, they have been queuing at checkpoints leading out of the city.

Transitional authority forces say they are observing a truce to encourage the remaining civilians to get out, before launching a final assault.

Sirte is one of two major cities still holding out against the National Transitional Council (NTC) forces.

The whereabouts of Col Gaddafi remain unknown. Jonathan Head reports from outside Sirte.
