A passenger ship carrying more than 470 people has sunk off South Korea's southern coast and a massive rescue operation is under way.
Officials say at least one person has been found dead, but that 147 people have been rescued so far from the ferry, which was headed to the popular resort island of Jeju.
South Korean television showed the boat leaning heavily to one side, and then slowly sinking almost completely under the water.
The Ministry of Security and Public Information says 34 rescue boats and 18 helicopters are involved in the rescue effort.
The reason for the crash is not clear. Some passengers reported hearing a loud noise before the ferry started sinking.
Most of the passengers were high school students headed to Jeju island on a school outing.
