MANAMA, Bahrain - The U.S. Navy says it has suspended the search for two missing airmen after a helicopter crash in the Red Sea. Three other crew members were rescued earlier.

A Navy statement Monday said officials determined the chance of survival was now considered "extremely unlikely" following Sunday's crash.

The MH-60S Knighthawk went down in the central Red Sea while operating with the destroyer USS William P. Lawrence.

The names of the missing airmen were not immediately released.

The Bahrain-based 5th Fleet says aircraft and vessels took part in the search. It said the crash was under investigation, but no hostile action was involved.
