A transcript of communications between the stricken Sewol ferry and the coastguard has lifted the lid on the final minutes before the order was given to abandon ship.
The conversations show panic setting in on board the vessel, with officers asking for help to "please come quickly" as it began to tilt to the left, three hours from its destination of Jeju Island.
The transcript also appears to back up claims that the evacuation order may have come too late for some passengers as officers said the ship was tilting so much it was "impossible to move" to check on them.
The communication, which begins with the first distress call made by the ferry on Wednesday morning, has been translated by The Associated Press.
