Sewol ferry disaster: Grief and anger one year on

A total of 304 people died a year ago when the ferry, Sewol, capsized and sank in South Korea.

Among the dead were 250 children from the same high school.

The captain of the ship has already been sentenced to 36 years in prison for gross negligence. But the verdict did not end the anger and pain of the relatives of those who died.
