Libya: Rebels call for more help from Nato

Anti-Gaddafi rebel fighters in Libya have called on Nato to offer them more assistance.

Pro-government troops have been shelling the port area in Misrata, the only city in the west of Libya that's held by rebels.

Across the country, Nato patrols and airstrikes are still trying to break the hold of forces loyal to Colonel Gaddafi.
