Four U.S. military personnel died when a KC-135 aerial refueling aircraft crashed near the Iraqi-Jordanian border during operations related to conflicts involving Iran, with two crew members still missing as rescue efforts continue. CENTCOM confirmed the crash was not due to hostile or friendly fire and noted a second KC-135 involved in the same operation was damaged but landed safely in Tel Aviv. This incident is the fourth U.S. aircraft crash linked to Operation Epic Fury, which has resulted in 11 U.S. service member deaths since February 28, and recovery operations are ongoing amid an active investigation.
