At least two U.S. troops were killed at the U.S. military’s Muwaffaq Salti Air Base in Jordan on July 17, with the remains of a third unidentified individual found at the same base.​The deaths at the Jordanian air base are the first Iranian-caused fatalities to occur in the war since March.

​Here’s a timeline of all incidents where U.S. troops have been killed during the war with Iran:March 1: Six troops killed at tactical operation center in Port of Shuaiba in Kuwait, one killed in separate attack in Saudi Arabia

​An Iranian drone hit the tactical operations center in Kuwait’s Port of Shuaiba, killing six Americans and injuring more than 20. The attack occurred hours after the war began on Feb. 28.​All six service members killed were reservists from the 103rd Sustainment Command, identified as: Capt. Cody A. Khork, 35; Sgt. 1st Class Noah L. Tietjens, 42; Sgt. 1st Class Nicole M. Amor, 39; Sgt. Declan J. Coady, 20; Maj. Jeffrey R. O’Brien, 45; and Chief Warrant Officer 3 Robert Marzan, 54.​The attack was the deadliest on American forces since the 2021 Abbey Gate bombing, which killed 13 troops in Afghanistan.​A soldier injured in the attack told CBS News that he thought the operations center had no fortification.​“I mean, I would put it in the none category. From a drone defense capability … none,” he said.
