The Khatam al-Anbiya joint military command in Tehran vowed to launch a campaign of sustained strikes against US assets across the region on Sunday. Iran's military headquarters stated that every American installation and economic interest in the Middle East would be targeted without restriction if Washington initiates renewed military action. Tehran claims the US is currently coordinating these plans at a meeting in Europe with the approval of certain regional allies.

The US Embassy in Manama and other diplomatic posts issued security alerts for US citizens, while the State Department released a worldwide travel caution. Iran warned that regional states aiding US aggression would be viewed as participants in the conflict and should not expect leniency from the Iranian armed forces. The security warnings coincide with reported shifts in presidential travel and military movements in the region.
