Secretary of State Hillary Clinton decided to end the Mujahedin-e Khalq (MEK) status as a foreign terrorist organization, despite its past terrorist attacks on American citizens, based on recent good behavior and a renunciation of violence.

“With today’s actions, the Department does not overlook or forget the MEK’s past acts of terrorism, including its involvement in the killing of U.S. citizens in Iran in the 1970s and an attack on U.S. soil in 1992.” the State Department said in a statement. “The Secretary’s decision today took into account the MEK’s public renunciation of violence, the absence of confirmed acts of terrorism by the MEK for more than a decade, and their cooperation in the peaceful closure of Camp Ashraf, their historic paramilitary base.”

The State Department said it still “has serious concerns about the MEK as an organization, particularly with regard to allegations of abuse committed against its own members.”
