New a new report, published on Thursday in the London-based journal The Jewish Chronicle, claims that the Israeli agency Mossad was behind the sabotage in Natanz, which allegedly destroyed 90 percent of the plant’s nuclear centrifuges. The journal said that a team of over 1,000 technicians, intelligence analysts and operations officers was behind the attacks. The latter were carried out in a variety of ways that included infiltrating supply chains, recruiting Iranian scientists, and deploying a so-called suicide drone.

According to the The Jewish Chronicle, in 2019 the Mossad managed to infiltrate the supply chains used by Iran to build additions to several buildings and underground facilities in Natanz. Consequently, Israeli intelligence operatives posing as construction material wholesalers were able to supply building materials to Iranian government officials, which were “filled with […] explosives”. These were detonated remotely in July 2020, causing substantial damage to the nuclear plant.

At around the same time, Mossad officers posing as Iranian dissidents began recruiting Iranian scientists working at Natanz. The Chronicle cites an unnamed source who says that “the scientists’ motivations were all different” and that the Mossad offered each of them “what they deeply wanted in their lives”. The Mossad supplied the recruited scientists with explosives, which were dropped into the Natanz compound by drones, or smuggled inside boxes of catering supplies. The bombs were “remotely set off” in April 2021 and almost completely destroyed Natanz’s A1000 underground centrifuge hall, which is buried beneath 12 meters of reinforced concrete. Following the attack, 10 Iranian scientists were “spirited away to a safe location. All of them are safe today”, according to the unnamed source.

Two months later, a third attack was carried out, this time against a manufacturing facility of the Iran Centrifuge Technology Company in the city of Karaj, which is located 30 miles northwest of the Iranian capital Tehran. The attack was reportedly carried out with the use of a loitering munition —also known as a suicide drone— the size of a motorcycle. Mossad operatives had previously managed to smuggle the device into Iran in small components, which were then re-assembled.

The Chronicle reports that the attacks against the Natanz nuclear plant were carried out by Israeli spies without the participation of American intelligence agencies. The journal also claims that Israel recently put in motion “a new policy of launching covert attacks on Iranian soil in retaliation for its meddling in the region”. This means that “further undercover operations [inside Iran] are in the pipeline”, the report concludes.
