Bahrain Mirror- Reuters: The U.S. State Department called on American citizens to "exercise increased caution" while travelling to Saudi Arabia, a travel advisory posted on its website said on Wednesday.

U.S. Mission personnel and their families are not permitted to use the airport in Abha without Chief of Mission approval, the note added.

Abha airport has been frequently attacked by drones and missiles launched from Yemen, where a Saudi-led coalition has been battling the Houthi group.
