The U.S. State Department on July 19, 2026, reiterated its worldwide warning for Americans traveling or residing overseas, amid concerns that Iran or its supporters may retaliate against U.S. citizens and interests. The 'Worldwide Caution' alert, active since February, advises U.S. citizens to remain vigilant and follow guidance from local U.S. embassies. This advisory follows recent events, including an Iranian missile and drone attack in Jordan that resulted in the deaths of two American service members and left another missing.
The U.S. Embassy in Amman also issued a security alert after Jordanian authorities evacuated Aqaba's international airport and seaport due to a credible threat. The embassy has advised Americans to avoid these locations and noted that non-emergency U.S. government personnel and their families have been under an ordered departure since March due to ongoing security risks.
The State Department characterized the security environment as 'complex' and warned that the conflict could escalate unexpectedly. Officials highlighted that U.S. diplomatic facilities have been targeted in the past and cautioned that supportive groups may target U.S. interests globally. Americans, especially in the Middle East, are urged to exercise caution, maintain a low profile, avoid U.S.-associated locations, and stay informed through local news and embassy alerts. The advisory also mentions potential disruptions to commercial flights due to ongoing military activity, advising travelers to check with airlines for updates.
