Trump announces that the United States has launched a large-scale military strike against Iran, aiming to destroy its military capabilities and nuclear projects and to promote regime change. Israel states that it is coordinating and synchronizing actions with the U.S.; explosions have been reported in multiple locations including Tehran, with Iran claiming it is preparing for retaliation. Israel has sounded air raid sirens nationwide and intercepted incoming missiles. The U.S. says the operation could last several days and is larger in scale than last June's strike on Iran's nuclear facilities, codenamed "Operation Epic Fury."
