The State Department renewed its warning on Saturday to Americans who may be traveling in and through the Middle East as escalating regional tensions raise concerns among travelers.
The warning came as Iran-backed Houthi rebels launched a ballistic missile toward Riyadh, Saudi Arabia, over the weekend — which Saudi Arabia said its air defenses intercepted.
Residents reported hearing an explosion and later seeing a plume of smoke near King Khalid International Airport, according to The Associated Press (AP). No casualties or damage from the attack were reported.

In an X post on Saturday, the State Department's Bureau of Consular Affairs warned that the security environment in the Middle East "remains complex with the potential for unforeseen escalation."
The agency added, "Americans currently in the Middle East should exercise heightened vigilance and be aware of potential flight cancellations, airspace closures, and travel disruptions."
Officials specifically cited hostilities between Saudi Arabia and the Iran-backed Houthis in its warning.
"Iranian-supported Houthis have engaged in hostilities against Saudi Arabia, including civilian airports," the post said.

"This military conflict has the potential to escalate rapidly. Americans outside the Middle East should seriously reconsider travel to and through the region."
The agency also advised those traveling to or from the region to monitor airport and airline operations, warning that U.S. diplomatic facilities have been targeted, including outside the Middle East.
"Iran and groups supportive of Iran may target other U.S. interests overseas or at locations associated with the United States and Americans throughout the world, including U.S. businesses and other institutions," the post added.
