SEOUL, South Korea — Twenty-five people have been confirmed dead in the sinking of a South Korean ferry, authorities said Friday.

The coast guard said another 271 people were still missing, the Yonhap News Agency reported.

“It seems like bodies have begun to spill out of the sunken ship due to current shifts,” Yonhap quoted an official as saying.

All bodies recovered to date were found floating in the sea rather than being recovered from the wreck of the ferry.

The Sewol sank on Wednesday while traveling from Incheon near Seoul, the capital, to the southern resort island of Jeju.
