The People’s Mujahedeen of Iran, more commonly known as the Mujahedeen-e-Khalq or MEK, is a controversial Iranian resistance group; it was once listed as a Foreign Terrorist Organization (FTO) by the United States for its alleged killing of U.S. personnel in Iran during the 1970s, and for its ties to former Iraqi leader Saddam Hussein. Recognizing the group’s rejection of violence, the State Department delisted the MEK in late 2012 but voiced ongoing concerns about its alleged mistreatment of its members.

The MEK helped Islamists overthrow the Western-backed Shah in 1979, but broke violently with the clerics shortly after the revolution and were forced into exile in France in 1981. The group moved its base of operations to eastern Iraq in 1986, but in recent years the pro-Iranian government of Nouri al-Maliki has pushed for the exiled group to relocate. In mid-2014, some 3,000 MEK members resided at Camp Hurriya (Liberty) near Baghdad, awaiting resettlement to third countries. […]

The MEK participated in the 1979 revolution that swept Ayatollah Khomeini into power, but refutes U.S. government claims that it also supported the hostage-taking raid on the U.S. Embassy in November of that year. “Though denied by the MEK, analysis based on eyewitness accounts and MEK documents demonstrates that MEK members participated in and supported the 1979 takeover of the U.S. Embassy in Tehran and that the MEK later argued against the early release [of] the American hostages,” said a 2011 State Department report on terrorism. […]

Feminism and allegiance to the Rajavi family are pillars of MEK ideology, which was founded on both Islam and Marxism—though the group has denied its affiliation with the latter.

Many analysts, including Rubin, have characterized the MEK as a cult, citing the group’s fealty to the Rajavis. Older women were reportedly required to divorce their husbands in the late 1980s, and younger girls cannot marry or have children. […]

Prior to the U.S. invasion of Iraq, Saddam was the MEK’s primary financier, experts say. But in recent years, the group claims to rely on the largesse of wealthy Iranian expatriates in the United States and Europe, and others opposed the clerical regime in Tehran. […]
