The controversial report was also published by the Iranian news agency Fars, under the title "Suspicious military activity of the Zionist regime in Saudi Arabia."
According to the report, the IDF built a military base approximately 9 km (5.5 miles) from Tabuk, and while Israeli planes landed there on June 18 and 19, all civilian flights were cancelled at the local airport.
One of the passengers in Tabuk noted that civilians at the airport were not given an explanation for the flight cancellations, but were compensated by the Saudi authorities and accommodated in nearby hotels.
The report further claimed that "the secret relations between Israel and Saudi Arabia became the main topic of conversation among the city's residents."
Another report published two weeks ago claimed Saudi Arabia tested its defense missile systems In order to allow IAF airplanes to pass through its airspace en route to bombarding nuclear facilities in Iran.
Security elements in the Persian Gulf told the London-based Times magazine that Riyadh gave Israel the green light to fly through a narrow airspace in the north of the country, in order to shorten the flight time to the Islamic Republic.
According to the Times, in order to ensure that IAF aircraft are not intercepted by Saudi defense missiles, Riyadh conducted tests to make sure the system does not activate if Israeli planes are detected. After the aircraft clear the area, the system will resume to normal activity.
