The U.S. military has confirmed that 10 U.S. troops were killed in the crash of two helicopters off the coast of Djibouti Friday.

A military statement Sunday says the dead include eight Marines and two Air Force airmen. Military officials said earlier that two service members rescued shortly after the crash were in stable condition.

On Saturday, the U.S. military said it had accounted for all 12 people aboard the helicopters, but it did not specify whether 10 of them were dead or alive.

It released Sunday's statement after notifying the dead troops' next-of-kin.

The two CH-53E helicopters were on a training mission when they went down in the Gulf of Aden. The troops were members of a U.S. counterterrorism force deployed in the Horn of Africa state.

The cause of the crash has not been determined. Military officials have said there was no indication of hostile fire.
