On Saturday, July 18, 2026, the State Department issued a “Worldwide Caution” alert advising Americans to exercise caution while living or traveling abroad due to increased threats against U.S. diplomatic facilities and tensions in the Middle East.
Worldwide Caution Alert
“Due to heightened tensions in the Middle East, the security environment remains complex with the potential for unforeseen escalation,” the statement read.
“We remind Americans in the region of the continued need for caution and encourage them to monitor the news for breaking developments. The Department of State advises Americans worldwide, and especially in the Middle East, to exercise increased caution,” it continued.
The State Department felt it was a necessary announcement after two U.S. service members were killed in Jordan from an Iranian attack, and four other American service members were “medically evacuated.”
Iran Military Retaliates
Iran pledged to retaliate against the U.S. since it has resumed strikes on their coastal surveillance and air defense facilities, in addition to their missile and drone storage sites.
“Now that the American enemy is seeking to escalate the conflict thereby incurring even heavier costs and further humiliation, it should know that the noble nation of Iran and the Resistance Front have unforgettable lessons in store for it,” Iran’s Supreme Leader Mojtaba Khamenei said.
The Islamic Revolutionary Guard Corps planned attacks on Saudi Arabia, Kuwait, Bahrain, and Jordan. Aqaba’s international airport was forced to be evacuated because of what officials described as a “specific and credible threat,” and simultaneously, Kuwait International Airport was hit with Iranian missiles and drones on various occasions.
“Americans abroad should follow the guidance in security alerts issued by the nearest U.S. embassy or consulate,” the State Department said Saturday. “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,” it added.
Exercise Safety and Caution
The department also encouraged the use of the Smart Travel Enrollment Program (STEP), in which Americans can enroll at step.state.gov to register their trips and receive the latest security updates from the nearest U.S. Embassy or Consulate in the area where they are traveling.
Regardless of whether they are enrolled in the program, officials strongly encourage travelers to check with their airline before departing and to prepare for any delays, reroutes, or last-minute cancellations, as security conditions could continue to change.
The State Department issues worldwide caution alerts only when it believes security threats extend beyond a single country or region. Although Americans are not prohibited from international travel, officials urge people to use caution, stay vigilant, and be prepared for changes in safety conditions while abroad as tensions in the Middle East continue to grow.
Tension in The Middle East
The escalating U.S. – Iran conflict stems from Iran’s threat to close the Strait of Hormuz, which would drive up oil prices past $90 a barrel due to the blockades that would disrupt shipping.
The U.S. is continuing to conduct a series of air strikes on the nation, following a deadly troop attack in Iraq. The U.S. recently launched its seventh consecutive nightly airstrike attack and will continue until Iran concedes.
Iran is retaliating by launching missiles and drones at U.S. military bases in their allied Gulf states. Kuwait and other Gulf locations have reported explosions and recent warning sirens.
In addition to the recent Worldwide Caution alert, U.S. officials urge Americans in Middle Eastern nations, including Bahrain, Egypt, Iraq, Israel, Jordan, and Saudi Arabia, to evacuate immediately due to the risk of attacks.
