NTC fighters cut off Sirte escape route

Libya's National Transitional Council fighters have reached the costal route in Gaddafi's hometown of Sirte, cutting off the last escape route for loyalists.

Gaddafi combatants are now surrounded in the city and are said to number no more than 2,000.

However, they are still putting up stiff resistance and inflicting casualties.

Al Jazeera's Tony Birtley reports from Sirte.
