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.

All 10 people aboard a small plane that went missing and was later discovered crashed in Alaska have been confirmed dead, officials said in a statement Saturday.

Crews are still working to recover the bodies of 10 people killed in a plane crash in Alaska, officials have said. Jennifer Homendy, chair of the National Transportation Safety Board, said the investigation into the crash was in its "early stages" and it was too soon to tell what caused it.
