A fourth service member has died after suffering injuries during Iran’s “initial” attack, the US military has announced.

“As of 7:30 am ET, March 2, four U.S. service members have been killed in action,” US Central Command said in a post on X. “The fourth service member, who was seriously wounded during Iran’s initial attacks, eventually succumbed to their injuries.”

The service member was killed in the same attack in Kuwait that earlier killed three others, one US official and a source familiar with the situation told CNN.

The identities of those killed will be withheld for 24 hours after next of kin is notified, CENTCOM said in the post.
