MANAMA (Reuters) - A female sailor was found dead at a U.S. naval base in the Gulf island kingdom of Bahrain on Sunday, the Navy said.

The cause of death was under investigation, and the name of the sailor was being withheld until the family had been notified, the Navy said in a statement. It gave no further details.

In October, two female sailors were killed and a third sailor was critically wounded with what appeared to a self-inflicted gunshot wound in a shooting incident at the base.

Bahrain is the home of the U.S. fifth fleet. About 3,000 staff live and work on the base, and generally keep a low profile in the tiny kingdom of about 1.05 million people.
