Baengnyeong Island, South Korea — Military divers plunged into the waters near South Korea’s tense maritime border with North Korea on Saturday, searching in vain for 46 missing marines from a naval ship that exploded and sank, officials said.
The exact cause of the explosion was unclear, but North Korea did not appear to be to blame, officials said.
Families voiced their anger as hopes faded for the missing crew after the ship sank in one of South Korea’s worst naval disasters. Divers tried twice to get to the wreckage, Rear Adm. Lee Ki-sik of the Joint Chiefs of Staff told lawmakers.
The explosion tore open the rear hull of the Cheonan, shut down its engine, wiped out power and caused the ship to sink a little more than three hours later, the Joint Chiefs said.
A survivor, Staff Sgt. Shin Eun-chong, 24, told relatives he was on night duty when he heard a huge boom behind him that split the ship apart. The vessel started tilting, and his glasses fell off his face as he hit the deck, relatives at a naval base in Pyeongtaek told The Associated Press.
Military planes and boats were searching the waters near South Korea’s Baengnyeong Island where the 1,200-ton Cheonan had been on a routine patrol mission. Rescue efforts Saturday were hampered by fierce waves and high winds.
“Yells and screams filled the air,” witness Kim Jin-ho, a seaman who was on a passenger ship bound for Baengnyeong, told cable news channel YTN. “Marines on deck were desperately shouting: ‘Save me!”’
Despite early fears of an attack, there was no immediate indication that North Korea — which lies within sight about 10 miles from Baengnyeong — was to blame, the Joint Chiefs said. Still, troops were maintaining “solid military readiness,” Vice Defense Minister Jang Soo-man said.
Earlier Friday, North Korea’s military threatened “unpredictable strikes” against the U.S. and South Korea in anger over a report the two countries plan to prepare for possible instability in the totalitarian country.
The ship went down near a disputed maritime border that has been the site of three bloody skirmishes between the Koreas, which remain in a state of war because their three-year conflict ended in a truce, not a peace treaty, in 1953.
President Lee Myung-bak ordered officials to make all efforts to rescue the crew, spokeswoman Kim Eun-hye said. “I can only imagine how much shock and pain the missing marines’ families must be in,” he said late Saturday, according to Kim.
Authorities have not confirmed any deaths, but Rear Adm. Lee told lawmakers he presumed most of the missing sailors were trapped inside, the Yonhap news agency said. A coast guard official said humans can survive in winter waters if they are rescued within two hours.
