Iran replaces top security official with Revolutionary Guard member.
Ali Shamkhani, a long-time ally of Iran's supreme leader, has stepped down as the country's top security official, two months after signing a China-brokered deal with Saudi Arabia to end a political rift. A Revolutionary Guards commander, Ali Akbar Ahmadian, has replaced Shamkhani. Shamkhani might be considered for a "more important position" in Iran.
