Libya conflict: Intense fighting in battle for Sirte

Libya's interim government forces say they have pro-Gaddafi troops "cornered" in two small areas of Sirte.

But heavy fighting continues the home town of fugitive former leader Col Muammar Gaddafi, as the loyalists put up fierce resistance.

The National Transitional Council (NTC) says that once Sirte falls, they will declare national liberation.
