Libya conflict: Heavy fighting continues

British Tornado jets have fired precision-guided missiles against a large bunker in Colonel Gaddafi's hometown of Sirte.

Libyan rebels are also building up their forces on the road to the town, sending tanks and rocket launchers there.

Meanwhile, the rebel leaders say they are moving their government from Benghazi in the east - to the capital, Tripoli, where sporadic fighting is still taking place.
