Iran’s Supreme Leader Ali Khamenei has replaced the chief commander of the Revolutionary Guards (IRGC), days after the United States designated the group a foreign terrorist organization. State TV announced the appointment of Brigadier General Hossein Salami to the position. "The Supreme Leader has appointed Salami as the new commander-in-chief of the Guards, who will replace Mohammad Ali Jafari," it said. Jafari had held the post since September 2007. President Donald Trump on April 8 designated the Guards a terrorist organization, in an unprecedented step. The designation took effect on April 15.
