JINDO, SOUTH KOREA (CNN) -- Divers have found no air pockets on the third and fourth floors of the sunken ferry Sewol, South Korean authorities said Wednesday.
The news all but eliminates any hopes of finding survivors on the ferry, which capsized and went down off the country's southwestern coast last week with hundreds of people on board.
Searchers had been focusing on the third and fourth levels of the five-floor vessel, as they believed many of those still missing were likely to be there. Most passenger bedrooms are on the fourth level of the now upended ship.
Earlier this week, divers and search officials had expressed hope they might still find air pockets that would have allowed people to survive in the submerged ship. They have insisted that their efforts remain a search and rescue operation. Authorities had said they thought a lot of passengers might have been gathered in the cafeteria on the third floor of the ferry. But early Wednesday, the coast guard said no bodies were found there.
Divers have nonetheless continued to bring bodies up from the murky waters, many of them found in rooms on the fourth floor, said Ko Myung-suk, a spokesman for the Joint Task Force coordinating the search.
He said there were still a lot of rooms left to search.
