Rescuers reached two trapped honeymooners in the interior of a cruise ship more than 24 hours after it ran aground off a picturesque Italian island, killing three people, injuring 20 and leaving dozens unaccounted for.
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.
With perhaps up to 50 people unaccounted for, divers suspended their efforts at dark, with plans to resume the search in the azure waters off the island of Giglio at dawn Sunday.
Accounts of the chaos from many of the 3,200 passengers were reminiscent of a maritime disaster 100 years ago this April -- the loss of the RMS Titanic.
"For me, the worst part of the whole ordeal" was when a lifeboat crew member told those boarding that it was "women and children first," said passenger Benji Smith of Boston.
"All these families who were clinging to each other had to be separated," Smith told CNN.
Some passengers fell into the chilly waters during the rescue, ANSA reported.
Questions abounded: Why was the colossal ship so close to the shore? How fast was it moving? How well did the crew respond? According to many passengers, the evacuation was disorganized and no one seemed in charge.
"Every crew member who walked past shouted instructions, but the instructions contradicted each other," Smith said.
Concordia's captain, Francesco Schettino, was interviewed earlier Saturday about what happened when the ship struck rocks in shallow water off Italy's western coast Friday evening, said officer Emilio Del Santo of the Coastal Authorities of Livorno. Local fishermen say the island coast of Giglio is known for its rocky sea floor.
Schettino said "that rock was not indicated on the chart," according to ANSA. "Me and the crew, we were the last to abandon ship," he said.
The ship was 2.5 miles off route when it struck the rocky sandbar.
"There are rocks, they are on the maps," said Capt. Cosimo Nicastro of the Italian Coast Guard. "What we know is the ship went really close to these rocks. ... We don't yet know why."
The ship began taking on water Friday evening and the crew kept going because they believed the vessel could normally keep sailing, Nicastro said. Realizing there was a significant safety problem, the commander steered the Costa Concordia closer toward port.
Authorities also were looking at why the ship didn't hail a mayday during the accident.
"At the moment we can't exclude that the ship had some kind of technical problem, and for this reason moved towards the coast in order to save the passengers, the crew and the ship. But they didn't send a mayday. The ship got in contact with us once the evacuation procedures were already ongoing," Del Santo said prior to the announcement of the captain's arrest.
Giuseppe Orsina, a spokesman with the local civil protection agency, said 43 to 51 people were missing, though authorities are reviewing passenger lists to confirm the exact figure.
"These people could be still on the island of Giglio, in private houses or in hospitals," Orsina said.
Two French tourists and a crew member from Peru were killed, Port authorities in Livorno said. One of the victims was a 65-year-old woman who died of a heart attack, according to authorities.
Nautilus International, a maritime employees trade union, called the accident a "wake-up call" to regulators.
"Nautilus is concerned about the rapid recent increases in the size of passenger ships -- with the average tonnage doubling over the past decade," said Nautilus general secretary Mark Dickinson in a statement. "Many ships are now effectively small towns at sea, and the sheer number of people onboard raises serious questions about evacuation."
Gianni Onorato, president of Genoa-based Costa Cruises, expressed "deep sorrow for this terrible tragedy," but said the cruise line was unable to answer all the questions that authorities are now investigating.
The vessel, plying the waters from Civitavecchia to Savona, Italy, struck a submerged rock, Onorato said in a statement before the announcement of the captain's arrest.
"Captain Schettino, who was on the bridge at the time, immediately understood the severity of the situation and performed a maneuver intended to protect both guests and crew, and initiated security procedures to prepare for an eventual ship evacuation," he continued. "Unfortunately, that operation was complicated by a sudden tilting of the ship that made disembarkation difficult," Onorato said.
