The assassination of Iranian top nuclear scientist Mohsen Fakhrizadeh is one of numerous assassinations in Iran conducted by foreign powers ever since 2007. In the past six months, assassins have in addition to Fakhrizadeh also been able to kill Al-Qaida’s no. 2 on Iranian soil. The three most important organizations in the Iranian intelligence community are the Ministry of Intelligence, as well as the Intelligence Organization and Intelligence Protection Organization of the Islamic Revolutionary Guard Corps. There is no doubt that the assassination of Fakhrizadeh is a counterintelligence failure; however, there are indications that the Iranian intelligence community have been compromised. The assassins of Fakhrizadeh had accurate information about Fakhrizadeh and his security details. Because of this breach, Iran will conduct serious reforms in its intelligence community and may also eliminate individuals it suspects work on behalf of foreign powers and may have leaked information.
