SEOUL, South Korea —
"We cannot give up," said South Korean President Park Geun-hye, after a briefing in Seoul with officials. "We have to do our best to rescue even one passenger."
Those rescued — wet, stunned and many without shoes — were brought to nearby Jindo Island, where medical teams wrapped them in pink blankets and checked them for injuries before settling them down on the floor of a cavernous gymnasium hall.
The ship had set off from Incheon, a city in South Korea's northwest and the site of the country's main international airport, on Tuesday night for an overnight, 14-hour journey to the tourist island of Jeju.
Three hours from its destination, the ferry sent a distress call at about 9 a.m. Wednesday after it began listing to one side, according to the Ministry of Security and Public Administration. Officials didn't know what caused it to sink and said the focus was still on rescuing survivors.
Lee Gyeong-og, a vice minister for South Korea's Public Administration and Security Ministry, said 30 crew members, 325 high school students, 15 school teachers and 89 non-student passengers were aboard the ship.
Kang Byung-kyu, a government minister, said two of the dead were a female crew member and a male high school student. He said a third body was also believed to be that of a student. A coast guard officer confirmed a fourth fatality but had no immediate details about it.
Kang said 55 were injured. Coast guard officials said 174 people were rescued and 284 were unaccounted for.
Yonhap news agency said the 146-meter (480-foot) -long ship, which travels twice a week between Incheon and Jeju, was built in Japan in 1994 and could carry a maximum of 921 people, 180 vehicles and 152 shipping containers.
The water temperature in the area was about 12 degrees Celsius (54 Fahrenheit), cold enough to cause signs of hypothermia after about 1½ hours of exposure, according to an emergency official who spoke on condition of anonymity citing department rules. Lee, the vice minister, said the ocean is 37 meters (121 feet) deep in the area.
