13 February 2006 :

the National Council of Resistance of Iran reported that a number of political prisoners, among them supporters of the People’s Mojahedin Organization of Iran (PMOI), had disappeared, according to family members and other prisoners.
Following the referral of the clerical regime’s nuclear file to the UN Security Council, prison guards had threatened Mojahedin prisoners that they would all be executed, the group said. Meanwhile, there were reports that Hojjat Zamani, a Mojahedin imprisoned since 2001, had gone missing.
