South Korea Ferry Disaster 'Tantamount to Murder'

The ferry Sewol sank in 27m of water in calm seas on Wednesday off as it sailed from Incheon in the northwest to the southern island of Jeju.

Lee Joon-Seok, the captain, was arrested on Saturday along with a helmsman and the ship's relatively inexperienced third officer, who was in charge of the bridge when the ship first ran into trouble.

Four more crew members were arrested on Monday, Al Jazeera's Adrian Brown reported from the island of Jindo in South Korea's southwest.

"The actions of the captain and some crew members were utterly incomprehensible, unacceptable and tantamount to murder," President Park Geun-hye was quoted as saying in a meeting with senior aides on Monday.

"Not only my heart, but the hearts of all South Koreans have been broken and filled with shock and anger."

Park said it was increasingly clear that Lee had unnecessarily delayed the evacuation of passengers from the Sewol as it started sinking, and then "deserted them" by escaping first.

"This is utterly unimaginable, legally and ethically," she said, adding that all parties to the disaster, from the owners, to the safety inspectors to the crew would be investigated and all those responsible would be held "criminally accountable".

Park had been heckled on Thursday when she met relatives of the hundreds of passengers still missing - most of them schoolchildren.

The families have criticised the official response to the disaster, saying the initial rescue effort was inadequate and mismanaged.

Of 476 people on board, 64 have been confirmed killed and 238 people are still missing.
