The U.S. State Department on Sunday issued a rare worldwide travel advisory warning American citizens to exercise extreme caution abroad following President Donald Trump’s airstrikes on three nuclear sites in Iran.
The strikes—described by international observers as “reckless”—have triggered immediate global backlash, prompting protests across multiple countries and raising fears of retaliatory attacks against American travelers and interests. In its alert, the State Department cited the potential for demonstrations targeting U.S. citizens and noted that escalating conflict in the Middle East has already led to periodic airspace closures and widespread travel disruptions.
“There is the potential for demonstrations against U.S. citizens and interests abroad,” the alert warned, adding that travelers should monitor local media and be prepared for rapidly changing conditions. “The Department of State advises U.S. citizens worldwide to exercise increased caution.”
The security alert followed Operation Midnight Hammer, a mission that saw U.S. B-2 stealth bombers strike Iranian nuclear facilities, marking a dramatic escalation in an already tense standoff between Israel and Iran. The Pentagon has yet to disclose the full scope of the mission, but global reaction has been swift and largely condemning. Iran has vowed retaliation, and Yemen has officially declared its entrance into the war alongside Iran.
Meanwhile, backlash toward the U.S. is not confined to the Middle East. Anti-American protests have emerged in Europe, Africa, and parts of Asia. Countries like Ukraine and Somalia—already deemed high-risk—remain on the State Department’s no-travel list, along with Iran and Israel.
Adding to the growing list of advisories, the State Department has also updated guidance for India, issuing a level-2 travel alert over concerns of “rape, violence, and terrorism.” The advisory explicitly warns women not to travel alone and highlights India’s high rates of sexual violence and terrorist activity at tourist destinations and public areas.
Sunday’s caution follows a series of similar alerts in the past two years, including advisories related to the Israel-Hamas conflict in 2023 and rising anti-LGBTQ+ violence in 2024. However, national security experts say the current warning is more sweeping and severe due to the rapidly shifting dynamics in the Middle East and the unprecedented nature of the U.S. strikes.
Travelers are urged to enroll in the State Department’s Smart Traveler Enrollment Program (STEP) to receive real-time updates from U.S. embassies and consulates. Additionally, American citizens abroad are advised to develop independent evacuation plans, as U.S. government assistance may be limited in certain regions.
U.S. officials are emphasizing vigilance.
“There’s no telling where the next flashpoint will erupt,” USA TODAY quoted a former senior intelligence official. “But Americans should be aware that we’re entering an extremely volatile period where simply holding a U.S. passport can make you a target.”
