The wrecked Italian cruise ship Costa Concordia is being raised in one of the biggest maritime salvage operations in history.
Workers are slowly lifting the vessel by pumping air into tanks attached to the ship.
The refloating operations is expected to take six or seven days.
The ship will then be towed to its home port, Genoa in Italy, where it will be scrapped.
The Concordia struck a reef off the Italian island of Giglio in January 2012 and capsized, killing 32 people.
