Washington, USA (Reuters): A U.S. Black Hawk helicopter crashed off the coast of Yemen on Friday during a training mission and a search was under way for one U.S. service member, the U.S. military said.
U.S. Central Command said in a statement that five other service members aboard the aircraft had been rescued after the crash, which took place about 20 miles (32 km) off the southern coast of Yemen at 7 p.m. (16000 GMT).
A U.S. official told Reuters that the cause of the crash was under investigation.
CENTCOM spokesman Colonel John Thomas said, “When the incident took place the helicopter was not very high above the water.”
The United States has been carrying out air strikes against al Qaeda in Yemen , with at least 80 launched since the end of February.
A small number of ground raids using U.S. Special Operations forces have also taken place, including one in January which resulted in the death of a U.S. Navy Seal.
There have been a number of aviation mishaps involving U.S military aircraft in the past few months.
Last month, a military transport plane crash killing 16 service members including elite special operations forces in northern Mississippi.
