Khalil Tahmasebi (Persian: خلیل طهماسبی) (14 February 1924 – 21 January 1955) was a carpenter and member of the Iranian fundamentalist group Fadayan-e Islam ("Self-Sacrificers of Islam" ), which has been described as "the first Shiite Islamist organization to employ terrorism as a primary method of political activism." On behalf of this group, Tahmasebi who was waiting in the crowd on 7 March 1951 when the Iranian Prime Minister, Ali Razmara , visited the Shah Mosque for a memorial service, fired three shots, assassinating Razmara. He was arrested at the scene. He was described as a "religious fanatic" by The New York Times . In 1952, he was freed by the Iranian Parliament during the premiership of Mosaddegh , his pending death sentence was quashed, and he was declared a "Soldier of Islam." According to Time , Tahmasebi "promptly rushed to the Hazrat Abdolazim shrine , wept joyously and said: 'When I killed Razmara, I was sure that his people would kill me.'" Following the 1953 Iranian coup d'état , Tahmasebi was re-arrested and tried for the assassination of Razmara; he was executed in 1955.
