The former chief of Iran's state television says there are operatives in intelligence organizations who have vast powers, but their identities remain unknown. Mohammad Sarafraz who resigned his post as head of IRIB (Islamic Republic of Iran Broadcasting) in May 2016 due to interventions in his organization's financial operations by Supreme Leader Ali Khamenei's son Mojtaba and former IRGC intelligence Chief Hossein Taeb, was one of the closest persons to Khamenei until then.
