WASHINGTON (Reuters) - A U.S. Navy helicopter went down off the Virginia coast on Wednesday and one of the five crew members has died, the military said.

A Coast Guard cutter and two helicopters were dispatched to the site.

One of the four people rescued and flown to a hospital in Norfolk has died, the Navy said in a Twitter feed.

None of the crew has been identified. The Navy statement said the cause of the crash was under investigation.

The helicopter was part of an anti-mine squadron based at Norfolk, Virginia.
