A third service member was reported missing in the attacks that killed Feehan and Gonzales. U.S. President Donald Trump has said the war is necessary to stop Iran from developing nuclear weapons. The first US military fatalities came soon after the war startedShortly after the U.S. and Israel began the war on Feb. 28, an Iranian drone strike at a civilian port in Kuwait killed six American soldiers. Later in March, six service members were killed when a KC-135 refueling aircraft supporting U.S. military operations against Iran crashed in Iraq.
