SEOUL, South Korea (AP) — South Korean officials say divers were battling strong currents and wind to search unopened rooms in a sunken ferry for 70 missing passengers.

Emergency task force spokesperson Ko Myung-seok said the divers would focus on opening up six rooms on the third and fourth floors Saturday while again combing places already searched.

The bodies of 230 victims have been retrieved; 189 were found inside the ferry while 41 were floating in the sea.

Task force spokesperson Park Seung-ki said families were worried about the condition of the bodies, given how much time has passed.

The South Korean passenger liner Sewol was carrying 476 people, mostly students from a single high school, when it sank on April 16. Only 174 people survived.
