Israeli media showed a video of a suicide drone hitting an Iranian anti-aircraft missile launcher. Israeli agents adopted the same strategy as Ukraine's attack on Russia's strategic bombers, smuggling a considerable number of suicide drones into Iran in batches and launching them near Iranian anti-aircraft missile deployment sites, ballistic missile units, and other important targets. This may also be one of the reasons why Iran's air defense forces performed poorly in this attack.
Due to the large number of internal traitors within Iran, it has become relatively easy for Israeli intelligence agencies to smuggle weapons. The successful assassination of high-ranking members of Iran's military and atomic scientists by Israeli agents has already indicated everything. Khamenei appears to have much less control over Iran than before, with various moles and traitors providing intelligence to Israel.
