I haven't seen any confirmation of this "Fox" News report.
Latest news I saw - mentioned the Saudi-prince has pressured the USA to intensify their attacks on Iran.
Anyway Iran is FULLY aware that ALL these Gulf States, foremost Saudi-Arabia are US serfs.
Not just due to geopolitical aspiration on behalf of SA and Iran, but additionally due to severe religious differences, the Gulf States especially Saudi-Arabia and Iran have never been friends. Any Muslim terrorist organization you have heard off are SUNNI - and not SHIITE (Iran).
Therefore It wouldn't come as a surprise to me, that actually Saudi-Arabia, pushed TACO to attack Iran, independently of the Zionists known "aspirations".
