It killed several of Iran's new leaders in the early years after the revolution, including the then President, Mohammad Ali Rajayee, Prime Minister, Mohammad Javad Bahonar and the Judiciary Chief, Mohammad Hossein Beheshti who were killed in bomb attacks by the MKO members in 1981.
Since the 2003 US invasion of Iraq, the group, which now adheres to a pro-free-market philosophy, has been strongly backed by neo-conservatives in the United States, who argued for the MKO to be taken off the US terror list.
The US formally removed the MKO from its list of terror organizations in September 2012, one week after Secretary of State Hillary Clinton sent the US Congress a classified communication about the move.
In September 2012, the last groups of the MKO terrorists left Camp Ashraf, their main training center in Iraq's Diyala province.
The MKO has assassinated over 12,000 Iranians in the last 4 decades.

The presence of former Saudi General Intelligence Directorate (GID) Chief (Turki al-Faisal) at the MKO meeting in Paris and his sympathy and companionship with them shows the age-old bond between Monafeqin (the Hypocrites as MKO members are called in Iran) terrorist group and the Saudi regime against the Islamic Revolution and the Iranian nation," Sharif said.
Also yesterday, former Iranian Deputy Foreign Minister Hossein Amir Abdollahian underlined that participation of Turki al-Faisal in the annual MKO gathering proves Riyadh's extensive support for terrorism.
We shouldn't doubt in the extensive relations between the Saudi intelligence body and Monafeqin (Hypocrites as the MKO members are called in Iran), specially in recent years," Amir Abdollahian, who is now an advisor to the Iranian foreign minister, said on Sunday.
He referred to Faisal's remarks in the annual gathering of the MKO in Paris on Saturday, and said, "Such comments confirm that extensive financial and security supports for terrorism have always been on Riyadh's agenda.
Al-Fardan has been arrested over an article during which he criticized Bahraini lawmakers for supporting the MKO terrorist group.
Al-Fardan, the Arabic-language Al-Wasat journalist, was interrogated over his article that criticized the Salafist Member of Parliament, Jamal Bouhassan, who attended the MKO meetings in Paris, and disclosed how Bahrain and its Parliament support the MKO terrorist organization's activities against Iran.
