Libyan fighters have made major progress into Sirte, the home city of toppled leader Muammar Gaddafi.

National Transitional Council (NTC) forces said on Sunday they had managed to take control of Al Giza district, where a large number of pro-Gaddafi forces were based, as well as the city's university, and Ibn Sina hospital.
Al Jazeera's Tony Birtley sent this update from the front-line in Sirte.
