Rescue workers have found the bodies of two more people killed in a cruise liner that crashed off the Tuscan coast.
The discovery brings the total number of people known to have died on the Costa Concordia to 15.
Officials said that the two women were discovered in an Internet cafe on the stricken ship on Monday, following the discoveries of two more bodies over the weekend.
Latest reports said that at least 17 of the 4,200 passengers on board at the time of the crash are still missing, and that only eight of the 13 bodies discovered so far have been identified.
Officials have said it is possible more than 17 bodies will be found due to unregistered passengers who may have been on board.
The clock is ticking for the search because the craft is perched precariously on a rocky ledge of seabed near Giglio, part of a seven-island archipelago.
"We are asking the 4,000 persons who were on board to give any information they can about any of the persons still missing," said Alain Litzler, a Frenchman who is the father of missing passenger Mylene Litzler.
"We need precise information to help the search and rescue teams find them."
Meanwhile authorities said that the pumping of fuel could proceed alongside the search of the 114,500 ton ship.
It was also reported that the owners of Costa Concordia have offered survivors of the tragedy a 30 per cent discount off future cruises.
The gesture – which has been branded “insulting” - comes as the firm battles to stave off lawsuits that are likely to cost it hundreds of millions of pounds.
More than 100 passengers are believed to be preparing to sue the owners of the ship.
As the firm tries to limit the damage from impending lawsuits, it has also been reported passengers are receiving phone calls asking if they need counselling, information about how to claim for lost valuables and offering full refunds for the doomed voyage.
Costa Cruises is owned by an American-based company, Carnival Group, and the class action suit will see survivors seeking a minimum of £100,000 each, it has been reported.
