Do we know yet what path this missile took? Was it fired from inside Iran? If not, it had to travel a LONG way, and if from Israel, over Syria, Iraq and Iran - over 800 miles without being detected. Astonishing.
Maybe it came from one of the submarines in the Red Sea. MBS hates the Iranians. So he won't care if a missile goes through the Saudi sky as long as somebody is giving him heads up.
Remember Israel has subs with cruise missiles...could have been launched from the Persian Gulf.
