Salvage crews have found human remains on board the Sewol ferry in South Korea.

A memorial service has been held for the families of the nine people still missing after it sunk almost three years ago.

Relatives of those missing want a more thorough investigation into what caused the vessel to sink and why more than 300 people died.
