The wreck of Italy's Costa Concordia cruise ship begins to emerge from water on September 17, 2013 near the harbour of Giglio Porto. Salvage workers attempt to raise the cruise ship today and tonight, in the largest and most expensive maritime salvage operation in history, so-called 'parbuckling', rotating the ship by a series of cables and hydraulic machines. Thirty-two people died when the ship, with 4,200 passengers onboard, hit rocks and ran aground off the island of Giglio on January 2012.
