The U.S. State Department on Saturday, July 16, issued a Worldwide Caution addressing heightened tensions in the Middle East connected to the ongoing Iran conflict. The advisory highlights risks to U.S. citizens and interests abroad stemming from the security situation.
“Due to heightened tensions in the Middle East, the security environment remains complex with the potential for unforeseen escalation. The Department of State advises Americans worldwide, and especially in the Middle East, to exercise increased caution,” the department said in an official announcement.
“Americans abroad should follow the guidance in security alerts issued by the nearest U.S. embassy or consulate. Flight cancellations and periodic airspace closures may cause travel disruptions. U.S. diplomatic facilities, including outside the Middle East, have been targeted. Groups supportive of Iran may target other U.S. interests overseas or locations associated with the United States and/or Americans throughout the world,” the advisory added.
It further advised Americans to review country-specific travel advisories, country information pages, and any recent security alerts on travel.state.gov before planning travel. It also recommends enrolling in the Smart Traveler Enrollment Program (STEP) to receive updates from the nearest U.S. embassy or consulate.
Separate country-specific advisories remain in effect and provide additional location-based guidance.

The Worldwide Caution follows Iranian missile and drone strikes on a U.S. base in Azraq, Jordan late Friday night. U.S. Central Command (CENTCOM) confirmed that two American service members were killed in the attack, with one additional service member reported missing. Four others received brief hospital treatment and were discharged, while minor injuries were treated on site.
The attack marks the first American fatalities in the conflict since early April.
In response, CENTCOM conducted additional strikes on late Friday night into Saturday morning, marking the seventh consecutive night of military operations targeting the Iranian regime. “U.S. forces employed fighter aircraft, aerial drones, and warships in addition to other assets,” CENTCOM said.
The strikes targeted surveillance sites, military logistics infrastructure, underground weapons storage, and maritime capabilities in Iran, largely in the nation’s south, along the vital Strait of Hormuz.
Iranian forces have conducted retaliatory actions, including the strikes on the Jordan base and additional attacks on other sites in the Gulf State. Iranian state media and officials have reported impacts on infrastructure in Iran, while U.S. sources have described targets as military in nature.
Both Iranian officials and President Trump have stated that the memorandum of understanding previously in place has been suspended amid the exchanges.
Military operations are expected to escalate as the ceasefire breaks down. CENTCOM continues to monitor the situation and has indicated further actions to address threats to regional stability and international shipping routes.
The State Department’s Worldwide Caution remains active, with Americans advised to maintain awareness of developments through official channels and to avoid unnecessary travel to higher-risk areas while monitoring for updates.
