A passenger ship carrying 475 people, mostly high school students, capsized in waters off South Korea's southwest coast Wednesday, leaving at least nine people dead and 287 others still missing, local media reported, quoting the central disaster and safety countermeasures headquarters.

A total of nine people, including a crew member, five high school students, two teachers and a passenger, have been confirmed dead at around 11 am local time Thursday, with 179 people rescued and 287 still missing.

The passengers aboard the sunken vessel included 325 high school students and 15 teachers who had been on the way for a four- day field trip. The ship departed from South Korea's western port city of Incheon Tuesday night for the southern resort island of Jeju.

Among the rescued, 78 were students from the Danwon High School in Ansan, a Seoul suburb. Almost 70 percent of those aboard were from the high school.

Divers tried five times overnight to make their way into the submerged hull to search for those missing, but rapid currents and low underwater visibility hampered their rescue operations, said Kang Byung-kyu, minister of security and public administration, who is coordinating the rescue efforts.

A total of 555 coastguard and navy divers were working at the scene, and 29 airplanes and helicopters as well as 169 rescue ships have been dispatched to join the research operations.

Kang said 101 people were sent to nearby hospitals for treatment, with five of them severely injured.

The death toll was expected to rise further as hundreds of passengers were still missing almost a day after the 6,825-ton passenger ship, "Sewol," capsized and sank off Jindo Island, near the southwestern tip of the Korean Peninsula, at around 11:30 am local time Wednesday.

Earlier, a Chinese women surnamed Han told Xinhua that her sister, 38, and a 39-year-old Chinese man were among those missing on the sunken ferry.

Showing a picture of her sister and her companion with the sea scene as background, the woman said it was taken on the ferry when they were on their way to Jeju island for vacation, adding the missing couple are migrant workers working in South Korea for years.

The Chinese Embassy in South Korea has asked relevant South Korean government agencies to help confirm if they were on board the ill-fated ferry.

The Coast Guard received the first distress call from an estimated student passenger of the ship at about 8:52 a.m. Wednesday, and the ship had remained afloat in the waters for about two and a half hours with its body tilting.

The Coast Guard said that most of those missing were believed to be trapped inside the sunken vessel, adding they have resumed search operations into the hull together with navy divers from 7 a. m. on Thursday.

The U.S. Seventh Fleet has sent its amphibious assault ship USS Bonhomme Richard, which has helicopters on board and was on a routine patrol off South Korea's west coast, to the scene at the request of the South Korean military.

The rescue operations would have troubles Thursday as it will rain and strong winds will blow near the area of the scene, according to the weather forecast.

Salvage operations will start as early as Friday morning as it will take time for three cranes to arrive at the scene. One crane ship will get there Friday morning to salve the submerged hull out of the waters, with the others set to arrive Friday night.

The vessel was believed to have run aground in the waters as some rescued passengers said the ship began leaning to the port side after making a thumping sound on the bow. The ferry veered off the route as it departed some two and a half hours later than schedule due to a heavy fog off the country's west coast.

Other rescued passengers said an announcement was made through the loudspeakers in the vessel warning them not to move as it would be dangerous. It was said to have raised the death toll as many passengers failed to escape from the vessel timely.

The ferry's original captain, who had gone on vacation, was replaced by a substitute surnamed Lee, who the ship's operator Chonghaejin Marine claimed is a veteran with eight years of experience on the Incheon-Jeju Island route.

This is the second accident involving a Chonghaejin Marine vessel in three weeks. Another Chonghaejin ferry hit a 7.93-ton fishing boat on March 28 en route from Incheon to Baengnyeong Island in the West Sea. The 396-ton ship was carrying about 140 passengers and no injuries were reported in the accident.
