Several hundred people remain unaccounted for after a ferry carrying 459 people capsized and sank off South Korea.
The ferry, carrying mainly school students, was travelling from the port of Incheon, in the north-west, to the southern resort island of Jeju.
The BBC's Lucy Williamson in Seoul said that witnesses had felt a "large thud" before the ship sank.
