The US State Department issued a global security warning on the 22nd, advising American citizens overseas to be vigilant.
The conflict between Israel and Iran has led to travel disruptions and periodic closures of airspace over the Middle East, the U.S. State Department said. The State Department advises U.S. citizens around the world to exercise caution due to the risk of demonstrations targeting U.S. citizens and interests overseas. When planning your trip, pay attention to travel advisories, country information, and the latest security alerts issued by the State Department.
