Rescuers have recovered six more bodies from the freezing waters of the Bering Sea, where a South Korean fishing boat sank.
The vessel began taking on water and went down in bad weather Monday, in the remote sea off the far eastern coast of Russia.
So far, seven bodies have been recovered. Seven were rescued. At least 46 remain missing, and officials warn time is running out to save them.
Five fishing ships that were in the area and a U.S. coastguard plane are taking part in the search. A U.S. rescue ship is due to arrive Thursday.
The Oryong 501 was built 36 years ago and is owned by the South Korean fisheries firm Sajo Industries.
The crew included 35 Indonesians, 13 Philippine nationals, 11 South Koreans and one Russian inspector.
Sajo Industries says the bodies found Wednesday are thought to be three Indonesians, two South Koreans and a Filipino.
