The US embassies in at least 10 Middle East countries, including the Gulf nations and Israel, on Saturday warned American citizens to exercise caution and "consider departing" as the tensions with Iran escalate.
"Americans in the region should consider departing, or be prepared to depart should there be escalation," said the alerts put out by the embassies.
"Due to heightened tensions in the Middle East, the security environment remains complex with the potential for unforeseen escalation," the message read.
The advisory urged American citizens to check flight details and follow safety advice from local authorities. It added that they should be prepared for flight cancellations, periodic airspace closures and potential travel disruptions.

"The Iranian regime is unpredictable, as seen by its recent decisions to attack areas in the region without warning or provocations as well as to expand attacks to areas not previously targeted (such as Egypt)," said a post on the US Embassy Jerusalem site.
