Military divers have searched in vain for 46 marines missing since a South Korean ship exploded and sank near the tense maritime border with North Korea.
The cause of the explosion was unclear, but North Korea did not appear to be to blame, according to Fox News.
Divers tried numerous times to get to the wreckage with no success, according to MSNBC.
Rescue efforts Saturday were hampered by fierce waves and high winds.
