Officials say a Russian ship with 11 people on board has gone missing in stormy seas off the nation's Pacific Coast.

The Emergency Situations Ministry said it received a signal Sunday from an emergency buoy of the freighter Amurskaya in the Sea of Okhotsk. The ship was en route from the coastal town of Neran to Feklistov Island in the Sea of Okhotsk.

Another ship, which was traveling nearby, was ordered to search for the missing freighter and its crew, but couldn't immediately locate it. An amphibious plane was sent to the area to help in the search.
