More time and money will be needed to safely remove the Costa Concordia cruise ship from the rocks off Tuscany where it capsized last year, Italian officials say.

On the eve of the first anniversary of the grounding, officials have stressed the unprecedented nature of the task given the size of the ship – 112,000 tons – its precarious perch on rocks off Giglio island, and the delicate marine environment. 2000 tons of fuel have been pumped out but sewage and tonnes of rotten food remain. 32 people died in the disaster.
