Divers searching submerged cabins found the bodies of two elderly men, trapped at an assembly point, on Sunday, the Italian Coast Guard said.
Throughout the day, Italian fire brigades circled the ship, resting on its side with a gash just below the waterline and a rock stuck in the hull, in small craft, tapping the hull and listening for responses from people trapped inside.
A couple, honeymooners from Korea, was found alive inside a cabin of the ship, said Luca Cari, a brigade spokesman, and taken to a local hospital.
Later, onlookers witnessed a dramatic helicopter rescue take place above the half-submerged ship off the coast of this resort island; an Italian man, later identified by media reports as a crew member, was airlifted from the ship, thought to have broken his leg.
The ship, carrying 4,200 passengers and crew on a weeklong Mediterranean cruise, slammed into an object, described as either a rock or coral, near the island on Friday night as passengers for the late seating had just started dinner, tucking into appetizers of grilled mushrooms and scallops.
