Misrata counting cost of struggle to free itself

Speculation continues that British and French attack helicopters are about to join the warplanes already in the air over Libya.

The Libyan city of Misrata is counting the cost of its struggle to free itself.

It has been visited by Bernard Henry Levy, the man credited with persuading French President Nicolas Sarkozy to join the air offensive against Col Gaddafi's forces.

The BBC's David Loyn reports from Misrata.
