Libya's growing humanitarian crisis

The western Libyan city of Misurata continues to be under siege by Muammar Gaddafi's forces.

Its only lifelines are the sea routes to Benghazi, Tunis, and Malta, from where a steady stream of supplies has been trickling in over the past few weeks.

However, supplies such as food and medicine are running short in Misurata, Libya's third largest city.

Al Jazeera's Jonah Hull and cameraman Craig Pennington, boarded a trawler carrying humanitarian supplies, for a 24-hour voyage to the city.
