Libya: On the edge of Misrata's 'no-go zone'

The prolonged conflict in Misrata between rebel fighters and forces loyal to Col Gaddafi has created a city where civilians are in constant danger.

The BBC has seen evidence that cluster bombs are being used against the rebels - a charge the Libyan government has denied.

Residents are also being targeted by snipers and the BBC's Orla Guerin reports from the edge of a street where several people have been killed.
