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.

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.

The U.S. Coast Guard HC-130 Hercules crew searched the area between White Mountain and Nome but did not find the missing plane, officials said on X.
