South Korea ferry: Arrests as President condemns ferry crew

South Korean President Park Geun-hye has condemned the conduct of some of the crew of the ferry that sank last week, calling it "akin to murder".

Her comments come as authorities confirm four members of the crew have been arrested, for leaving the ship before the evacuation was complete. The captain has already been arrested.

The BBC's Jonathan Head says the fact that the disaster is being felt as a national tragedy means that the president has to show solidarity with the families.
