Junior officer \\\'had Korea ship helm\\\'

The third officer was at the helm of the ferry that capsized off South Korea, investigators said, as divers worked to access the sunken hull. A total of 268 people - including scores of high school students - remain missing after Wednesday's disaster. Twenty-eight people are now known to have died and 179 were rescued. It is not clear why the ferry sank, but experts have suggested it either hit a rock or turned sharply, unbalancing the vessel as cargo shifted. The vessel - named Sewol - had been travelling from Incheon, in the north-west, to the southern resort island of Jeju. It capsized and sank within a period of two hours, officials said, according to BBC.
