ROME - Salvage workers have found four more bodies on the wreck of the Costa Concordia, bringing to 21 the confirmed number of dead from the accident in which the huge cruise ship hit rocks and capsized off the Italian coast last month. Authorities said on Wednesday that the bodies of a woman and a 5-year-old girl had been recovered. Work on bringing the other bodies up from one of the sunken decks of the ship was continuing, they said. “It would seem that there are four bodies, recovery operations are underway,” the Civil Protection Agency said in a statement. Following the discovery of the bodies on Wednesday, 11 people remain to be accounted for.
