The U.S. government early on Tuesday issued a “worldwide caution” alert, warning that the security situation remains “complex” and that Iran and its terror proxies may target American interests overseas.
“Due to heightened tensions in the Middle East, the security environment remains complex with the potential for unforeseen escalation,” according to the statement.

“Americans currently in the Middle East should exercise caution and heightened vigilance and should be prepared for possible flight cancellations, periodic airspace closures, and potential travel disruptions,” it continued. “Please monitor embassy and consular security alerts, local authorities, and the news for breaking developments. Americans outside the Middle East should reconsider travel to and through the region.”

The statement noted that U.S. diplomatic facilities, including those outside the Middle East, have been targeted.
