More than 48 hours after the 6,825-tonne Sewol suddenly listed and then sank, a small of army of more than 500 exhausted divers -- battling powerful currents in almost zero visibility -- have yet to obtain any access to the ferry's interior.
The confirmed death toll stood at 28, but the focus of concern remained the 268 people still unaccounted for -- hundreds of them children on a high school outing to the southern resort island of Jeju.
"Two divers are currently injecting oxygen into the ship," a coastguard official said.
The only visible piece of the ferry, a small stern section of the keel, slipped just below the surface on today afternoon.

Of the 475 people on board when the Sewol capsized, 179 were rescued, but no new survivors have been found since Wednesday.
"I want to be clear: There won't be any salvage work done against the will of the families," he said.
There were 352 students on board and for the parents of those who were not rescued there was bitter resentment at what they saw as the inadequacy of the official response.
"It's been two days but no one has been brought out alive," complained Lee Yong-Gi, whose son was among the missing students.
Another father accused the authorities of indifference and deception in an appeal broadcast live on television.
