The South Korean passengers, each 29, heard searchers calling out on the Costa Concordia, Italy's ANSA news agency reported early Sunday. They were located in a cabin and taken ashore. Video showed them being taken to a waiting ambulance.
The captain of the ill-fated vessel, which turned over on its side after the grounding, was arrested late Saturday and was being investigated for abandoning ship and manslaughter, a local prosecutor said.
