According to the official, Mossad agents set up a drone base on Iranian soil near Tehran.
Israel spent years preparing for the operation against Iran’s nuclear and missile programs, including building a drone base inside Iran and smuggling precision weapons systems and commandos into the country.
The Mossad established a base for explosive-laden drones that were smuggled deep into Iran long before the attack.
During the Israeli strike, the explosive drones were activated and launched toward surface-to-surface missile launchers located at the Asfajabad base near Tehran.
