The US State Department issued a worldwide security alert Sunday advising American citizens, particularly those in the Middle East, to exercise "increased caution" as the Iran war enters its fourth week. The advisory warned that groups aligned with Iran may target US interests and locations associated with Americans globally. Threat level elevated The alert noted that US diplomatic facilities outside the Middle East have already been targeted in the ongoing conflict. The State Department also warned of periodic airspace closures that could cause travel disruptions, urging Americans abroad to follow guidance from the nearest US embassy or consulate. The advisory reflects growing concern about the conflict's potential to spill over beyond the immediate region. Escalating conflict The warning comes as US-Israeli strikes against Iran, which began Feb. 28, have reportedly killed at least 1,300 people including former Supreme Leader Ayatollah Ali Khamenei. Iran has retaliated with sustained drone and missile strikes targeting Israel, Jordan, Iraq and Gulf countries hosting US military assets, raising fears of further attacks on American interests worldwide. Global precautions The worldwide security alert underscores the expanding scope of the conflict and the potential for Iran-aligned groups to strike US targets far from the Middle East. With no diplomatic resolution in sight and military operations continuing, the State Department's warning signals heightened risk for American citizens and facilities across the globe.
