Bahraini Foreign Minister Khalid bin Ahmed bin Mohammed Al Khalifa tweeted a link to this, which is fairly remarkable. A strong indication of where the Gulf States stand with regard to Iran, this suggests that the Saudis would indeed not want to take down Israeli planes.
From the time of the horrendous attack in Bourgas, Bulgaria, which killed five Israelis and their Bulgarian bus driver, PM Netanyahu has been saying that this was the work of Iran, via its proxy Hezbollah in Lebanon. Things have been quiet for a while -- with little progress reported on identifying the perpetrator(s) of the terror attack.
Now, according to the NYTimes, "Israeli intelligence has evidence of many telephone calls between Lebanon and Bourgas in the two months before the bombing, according to a senior government official who spoke on the condition of anonymity because the information is classified, with the volume intensifying in the three days leading up to it."
To reveal what is known is to expose sources in the field, and so this is a sensitive investigation. But the link seems clear.
