Iranian President Hassan Rouhani said Tuesday that the United States was the real “leader of world terrorism” after Washington blacklisted Iran’s Revolutionary Guards as a “foreign terrorist organisation”. “Who are you to label revolutionary institutions as terrorists?” Rouhani asked in a speech broadcast live by state television. Speaking at a ceremony to mark Iran’s national nuclear technology day in Tehran, Rouhani defended the Revolutionary Guards as a force that has fought terrorism ever since its creation in 1979.
