The report by Nour News comes after weeks of speculation in the media and political circles about Shamkhani’s decision to resign.
Shamkhani has been holding the key post for a decade.
Media reports say Saeed Jalili who was secretary of the Supreme National Security Council from 2007 to 2013, will replace Shamkhani.
Jalili is currently a member of Iran’s Expediency Discernment Council.
