The US Department of State has issued a worldwide caution, urging Americans to avoid travel to the Middle East due to “the potential for unforeseen escalation”.

“Due to heightened tensions in the Middle East, the security environment remains complex, with the potential for unforeseen escalation,” the official announcement warned.

It also urged Americans currently in the Middle East to exercise caution, remain highly vigilant, and be prepared for flight cancellations, periodic airspace closures, and potential travel disruptions.

The alert noted that some airlines in the region had already postponed the resumption of previously suspended flight schedules, while others had cancelled certain routes.
