Suppression of opposition

In a talk at the Fayzieah School in Qom on 30 August 1979, Khomeini warned pro-imperialist opponents: "Those who are trying to bring corruption and destruction to our country in the name of democracy will be oppressed. They are worse than Bani-Ghorizeh Jews, and they must be hanged. We will oppress them by God's order and God's call to prayer."

However, in 1983, the Central Intelligence Agency (CIA) helped him by providing a list of Soviet KGB agents and collaborators operating in Iran to Khomeini, who then executed up to 200 suspects and closed down the Communist Tudeh Party of Iran.

The Shah Mohammad Reza Pahlavi and his family left Iran and escaped harm, but hundreds of former members of the overthrown monarchy and military were executed by firing squads, with exiled critics complaining of "secrecy, vagueness of the charges, the absence of defense lawyers or juries", or the opportunity of the accused "to defend themselves." In later years these were followed in larger numbers by the erstwhile revolutionary allies of Khomeini's movement—Marxists and socialists, mostly university students—who opposed the theocratic regime. From 1980 to 1981, the People's Mojahedin Organization of Iran and other opposition groups (including leftist and moderate groups) rallied against the takeover of the Islamic Republic Party through large demonstrations. On Khomeini's order, the Islamic Republic responded by shooting the demonstrators and arresting them, including their leaders. The 1981 Hafte Tir bombing escalated the conflict, leading to increasing arrests, torture, and executions of thousands of Iranians. Targets also included "innocent, non political civilians, such as members of the Baha'i religious minority, and others deemed problematic by the IRP." The number of those executed between 1981 and 1985's "reign of terror" is reported to be between 8,000 and 10,000.

In the 1988 executions of Iranian political prisoners, following the People's Mujahedin of Iran unsuccessful operation Forough-e Javidan against the Islamic Republic, Khomeini issued an order to judicial officials to judge every Iranian political prisoner (mostly but not all Mujahedin) and kill those judged to be apostates from Islam (mortad) or "waging war on God" (moharebeh). Almost all of those interrogated were killed, 1,000 to 30,000 of them. Because of the large number, prisoners were loaded into forklift trucks in groups of six and hanged from cranes in half-hour intervals.
