Including in the duties of MOIS is the tracing and recognition of persons who have contacts with the opposition groups abroad. Supporters of the most important group i.e. Mojahedin-e Khalgh, are more then anyone else, and particularly, subject of attention of Iran’s secret service. The Ministry of Intelligence tries to collect as much information about this organization as possible through “ex-members of the Mojahedin”. Also, the agents of MOIS are instructed to distribute negative information about PMOI and its members. In this way, they attempt to weaken the organization and, in order to end their social and political movements, strive to portray a satanic view of the Mojahedin in host countries.
