Reports from Russia say at least four people have been found dead and 49 were missing after a floating oil-drilling platform capsized and sank off the Russian Far East island of Sakhalin.
The Kolskoye oil rig platform was 200 kilometers from the shore when the accident occurred early on December 18 amid high winds and freezing temperatures.
Reports say a total of 67 crew members were believed to be on board when the platform overturned.
Officials are quoted as saying 14 crew members were rescued from the wreck of the platform, but the fate of other crew members was not immediately clear.
Russia has two major offshore projects that are producing oil off the island of Sakhalin: Sakhalin-1, operated by ExxonMobil, and Sakhalin-2, in which state-controlled gas export monopoly Gazprom has a controlling stake.
