Contact the FAA International Field Office used to be JFK details on the FAA website, I believe they provide safety oversight for Saudi DCA, they'll jump it so quick you wouldn't believe...under the circumstances I would think.
If they dont have the safety oversight connection any longer they'll no doubt inform Saudi DCA of your concerns through the proper and direct channels.
