Two U.S. servicemembers were killed and several were wounded in an Iranian attack on an air base in Jordan, further escalating a weeklong exchange of fire where both sides have been striking a broader array of targets. U.S. Central Command, which oversees American forces in the Middle East, confirmed the deaths and said another servicemember is missing as a result of the attack. Four servicemembers were medically evacuated to Jordanian hospitals and have since been discharged, according to Centcom. Other personnel who were evaluated for minor injuries have been returned to duty, Centcom added.
