A U.S. Navy helicopter has crashed in the Red Sea, carrying a crew of five, the military service says. The status of the crew is not yet known; a search and rescue effort was begun after the crash Sunday, using boats and aircraft.
"The crash was not due to any sort of hostile activity," the Navy says. "The incident is under investigation."
The helicopter, a MH-60S Knighthawk, had been on operations with a guided-missile destroyer, the USS William P. Lawrence. It is part of Helicopter Sea Combat Squadron Six.
