Capt. Cosimo Nicastro said Saturday divers are helping carry out a risky operation to inspect the submerged half of the Costa Concordia in case anyone remained trapped inside.
Nicastro tells Sky TG24 TV there are no firm indications that any one was trapped. But he notes rescuers carried out an extensive search of the waters near the ship for hours and "we would have seen bodies."
He says "the place where they might be is in the belly of the ship."
Three bodies were recovered after the cruise ship with more than 4,200 people aboard ran aground off the tiny island of Giglio late Friday.
