Libya conflict: Fighting continues around Sirte

The forces of Libya's transition government have clashed with supporters of ousted leader Muammar Gaddafi in one of his last strongholds, Sirte.

Black smoke was seen rising from the coastal city after National Transitional Council (NTC) soldiers entered from both the west and east.

Alastair Leithead reports from near Sirte, where he is with forces loyal to the transition government.
