U.S. Issues Global Travel Alerts Amid Escalating Iran Conflict

The United States Department of State issued a series of worldwide travel advisories between July 18 and July 20, 2026, warning American citizens to exercise increased caution due to a complex security environment in the Middle East. The alerts followed a July 17 Iranian missile and drone strike on a U.S. base in Jordan that killed two service members and left a third missing. The State Department warned that groups supportive of Iran might target U.S. diplomatic facilities and interests globally, including in Europe and Asia.

The conflict follows the collapse of a Pakistan-brokered 14-point Memorandum of Understanding signed in June intended to end hostilities. In response to the Jordan attack, U.S. Central Command executed strikes against the Islamic Revolutionary Guards Corps for seven consecutive nights, targeting surveillance facilities and weapons storage. Iran retaliated with missile and drone attacks against U.S. bases and infrastructure in Saudi Arabia, Kuwait, Bahrain, and Jordan. Major General Mohsen Rezaei warned that Tehran would launch "full-scale offensive operations" if U.S. attacks persisted.

By July 20, tensions peaked as the U.S. Embassy in Bahrain warned of imminent attacks in central Manama, coinciding with the activation of missile alert sirens across the country. Regional disruptions intensified, including the closure of Kuwaiti airspace through August 4 and the evacuation of Aqaba's international airport and seaport in Jordan. The United Kingdom and Canada also tightened travel advisories for the region, citing renewed military activity.
