Libya: Civilians try to escape Sirte

Anti-Gaddafi soldiers at checkpoints outside Sirte in Libya are trying to catch loyalists as they flee.

Sirte is the home town of fugitive leader Col Muammar Gaddafi and fighters have cornered his followers in a small area of the city.

Nato is carrying out air strikes over Libya under a UN resolution to protect the civilian population. It has vowed to continue until the former regime no longer poses a threat.
