The plane operated by Bering Air was carrying nine passengers and a pilot from Unalakleet to Nome in northwestern Alaska when it went missing, officials say.

Authorities are working to recover the wreckage of a plane crash in western Alaska that killed 10 people while investigators are trying to determine what caused the small commuter aircraft to go down in the icy Bering Sea.

The U.S. Coast Guard in Alaska found the wreckage of a small plane atop frozen sea ice on Friday, after the aircraft suddenly lost altitude on Thursday and the crash killed all 10 people on board, officials said.
