Hundreds of protesters take to the streets of Tehran on 12 April, to march against the United States' decision to designate Iran's Islamic Revolutionary Guard Corps (IRGC) a terrorist organisation.
The IRGC was founded in 1979 to counter left-wing opposition groups. Presently, IRGC has a wide range of responsibilities, such as providing domestic security, overseeing the activities of political, social and non-governmental organisations and private companies, preventing foreign interference and controlling Islamic norms of life and morality.
