Mossad activities in Iran

Mossad activities in Iran refer to the operations conducted by Israel's foreign intelligence agency, the Mossad, within or targeting the Islamic Republic of Iran. These activities have primarily focused on Iran's nuclear program, military infrastructure, and senior officials, amid longstanding tensions in Iran–Israel relations. Reports from various sources indicate that Mossad has engaged in espionage, sabotage, cyber attacks, and targeted assassinations, often in collaboration with other entities such as the United States intelligence community. Iranian officials have repeatedly accused Israel of these actions, while Israel rarely confirms or denies involvement, maintaining a policy of ambiguity.

The operations are part of a broader Israel–Iran proxy conflict, which has escalated since the early 2000s. Key events include the joint U.S.-Israeli Stuxnet cyber attack on Iranian nuclear facilities around 2010, the theft of Iran's nuclear archive in 2018, and a series of assassinations of Iranian nuclear scientists between 2010 and 2025. More recent activities reportedly played a role in the 2025 Israel–Iran War, including the assembly of drones and missiles inside Iran and the targeted killings of high-ranking Iranian figures, such as Supreme Leader Ali Khamenei in March 2026. These efforts have been credited with delaying Iran's nuclear ambitions but have also heightened regional instability.
