U.S. embassies in the Middle East, including Jerusalem, issued a joint security alert to American citizens in the region, urging heightened vigilance "due to the complex security situation." The State Department noted that the Houthis attacked critical infrastructure and civilian airports in Saudi Arabia and warned that the fighting could escalate rapidly. It was also noted that Iran and groups supporting it may target American interests, businesses and institutions worldwide. The alert clarified that flight cancellations, airspace closures and additional travel disruptions are possible.
