On Aug. 1 the U.S. embassy in Jordan issued a security alert saying regional
security remains complex and could further escalate. It advised U.S. citizens in
the Middle East to remain vigilant and prepare for possible flight
cancellations, temporary airspace closures and travel disruptions; those outside
the region should reconsider travel or transit through the area. The embassy
also urged U.S. citizens to avoid U.S. military bases in Jordan and areas with
heavy security deployments.
