Pictures: The Costa Concordia salvage operation

After twenty months of lying in the water, the shipwreck of the Costa Concordia is being raised upright in a massive operation of cranes and machinery.
The plan is to have the ship upright by Monday evening after a twelve-hour operation. If it is successful, the ship will be towed away and scrapped.
