The U.S. State Department has reiterated its worldwide caution for Americans abroad, citing escalating tensions with Iran and the potential for retaliation against U.S. citizens and interests globally. The advisory, which has been in place since February, warns that groups supportive of Iran could target Americans and U.S. facilities outside the Middle East.

This updated warning follows a recent Iranian missile and drone attack in Jordan that resulted in the deaths of two American service members and left another missing. U.S. Central Command reported carrying out airstrikes against Iran on Friday, July 17, 2026, in response to earlier attacks.

The security environment is described as "complex" with the potential for rapid escalation. The State Department noted that U.S. diplomatic facilities, even those outside the Middle East, have been targets in the past. The advisory urges U.S. citizens overseas to remain vigilant, monitor local developments, and follow guidance from U.S. embassies.

Specifically, Americans are advised to maintain a low profile, avoid locations associated with the United States when possible, and monitor local news and security alerts. Enrollment in the Smart Traveler Enrollment Program (STEP) is encouraged to receive security updates and allow embassies to contact citizens during emergencies.

In Jordan, the U.S. Embassy in Amman issued a separate security alert after Jordanian authorities evacuated Aqaba's international airport and seaport due to a "specific and credible threat." The embassy recommended that Americans avoid these locations. The State Department had already advised an ordered departure of non-emergency U.S. government personnel and their families from Jordan in March due to ongoing security risks.

The advisory also warns of potential travel disruptions, including commercial flight cancellations and temporary airspace closures, due to continued military activity. Travelers are encouraged to check with airlines before departure and prepare for possible itinerary changes. The State Department issues worldwide caution alerts when security threats are believed to extend beyond a single country or region, reflecting concerns that the current conflict could create security risks well beyond the Middle East.
