U.S. State Department Announces Worldwide Caution Alert After Two U.S. Service Members Are Killed By Iranian Strike

The U.S. State Department has issued a warning to U.S. citizens all across the globe.

Shortly after it was reported two U.S. Service members were killed in Jordan by an Iranian strike, the U.S. State Department issued a caution alert for Americans outside of the country.

The State Department also warned of flight delays due to potential air space closures as the conflict between the United States and Iran heats up.

Fox News reported more on the State Department’s announcement:

The State Department on Saturday issued a worldwide caution for Americans, citing heightened tensions in the Middle East and the potential for further escalation.

The department advised Americans worldwide—and especially those in the Middle East—to exercise increased caution, monitor local developments and follow security alerts issued by the nearest U.S. embassy or consulate.

The advisory warned that flight cancellations and periodic airspace closures could disrupt travel as the conflict continues.

The State Department also cautioned that U.S. diplomatic facilities, including those outside the Middle East, have been targeted and warned that groups supportive of Iran could target other U.S. interests overseas or locations associated with Americans.

The department encouraged Americans traveling abroad to enroll in the Smart Traveler Enrollment Program (STEP) to receive the latest security alerts and review travel advisories before departing.
