Libya: Gaddafi loyalists remain defiant

Forces loyal to Col Muammar Gaddafi continue to hold out in two of their strongholds.

In the town of Bani Walid, they fired rockets and mortars at anti-Gaddafi fighters, forcing them to retreat. There have also been fierce clashes around Gaddafi's hometown of Sirte.

The BBC's Alastair Leithead has been following the opposition forces.
