Divers have found the body of a woman in the wreck of the cruise ship Costa Concordia, bringing the number of people confirmed dead to 13.

Italian fire service divers found the body on deck seven of the vessel, about 10m below the water line, Italy's Civil Protection Authority said.

Rescue workers are still looking for 20 people who are believed to be missing.

The vessel sank on 13 January after hitting rocks near the island of Giglio, off Tuscany.

The woman who has now been found was wearing a life-jacket, officials say. Her body is being removed from the ship.

Only eight of the 13 bodies discovered have so far been identified.

Four of the victims were French, one was Italian, one Hungarian, one Spanish and one German, officials say.

The identity of a woman whose body was found on Saturday has yet to be established, along with those of three men discovered previously.

The head of the Civil Protection Agency, Franco Gabrielli, said the woman may be a Hungarian who was reported missing but was not on the ship's embarkation list.

There could have been more "illegals" on board, he said, referring to people who were not registered to be on the vessel.

Unauthorised course

There were known to be 4,200 people on the cruise ship when it got into trouble.

The captain, Francesco Schettino, is being detained under house arrest while his actions are investigated.

He is accused of multiple manslaughter, causing a shipwreck, and abandoning ship before all passengers were evacuated. He denies the allegations.

Prosecutors say the 57-year-old was sailing too close to Giglio on an unauthorised course in order to perform a "salute" - a greeting to islanders.

The Italian media have released a new recording in which Capt Schettino appears to say he will be the last to leave the ship.

In a previously released tape an official is heard repeatedly ordering him back on board.

Time pressures

Coastguard and navy divers have been blasting their way into submerged areas of the vessel using explosives in an effort to find those unaccounted for.

Emergency officials said on Saturday they would not end the search until the whole ship had been examined.

Work has been suspended several times due to poor weather.

On Saturday rescuers halted their search of the submerged parts of the ship due to rough sea conditions, but they were allowed back in on Sunday.

More than 600 members of the Italian emergency services are working on the search operation.

Correspondents say they are under time pressure, amid fears the ship could slip off a ledge into deeper water with a risk of fuel tanks being ruptured.

One official said swift action was needed to remove the fuel. An Italian naval vessel is on standby as a precaution should there be an oil leak.

Although there has been no leak so far, the civil protection agency says there is pollution in the water from solvents and disinfectants which were on board the vessel.
