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, around 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. Minority religions Zoroastrians, Jews, and Christians are officially recognized and protected by the government. Shortly after Khomeini's return from exile in 1979, he issued a fatwa ordering that Jews and other minorities (except those of the Baháʼí Faith) be treated well. In power, Khomeini distinguished between Zionism as a secular political party that employs Jewish symbols and ideals and Judaism as the religion of Moses. Senior government posts were reserved for Muslims. Schools set up by Jews, Christians and Zoroastrians had to be run by Muslim principals. Conversion to Islam was encouraged by entitling converts to inherit the entire share of their parents (or even uncle's) estate if their siblings (or cousins) remain non-Muslim. Iran's non-Muslim population has decreased. For example, the Jewish population in Iran dropped from 80,000 to 30,000. The Zoroastrian population has also decreased, due to suffering from renewed persecution and the revived legal contrasts between a Muslim and Zoroastrian, which mirrors the laws that Zoroastrians experienced under earlier Islamic regimes. The view that Zoroastrians are najis ("unclean") has also been renewed. Four of the 270 seats in parliament were reserved for each three non-Muslim minority religions, under the Islamic constitution that Khomeini oversaw. Khomeini also called for unity between Sunni and Shi'a Muslims. Sunni Muslims make up 9% of the entire Muslim population in Iran. One non-Muslim group treated differently were the 300,000 members of the Baháʼí Faith. Starting in late 1979 the new government systematically targeted the leadership of the Baháʼí community by focusing on the Baháʼí National Spiritual Assembly (NSA) and Local Spiritual Assemblies (LSAs); prominent members of NSAs and LSAs were often detained and even executed. "Some 200 of whom have been executed and the rest forced to convert or subjected to the most horrendous disabilities." Like most conservative Muslims,
