The search of the cruise ship grounded off the coast of Italy has been suspended after another setback.

Divers looking for the 21 passengers still missing from the Costa Concordia have had to stop after the ship's position shifted.

The vessel is grounded on rocks off the island of Giglio, but there are fears that it could slip off the shelf if it continues to move.

Al Jazeera's Paul Brennan reports from Giglio.
