Iran Security Chief Shamkhani Replaced After Decade of Service To Pursue Bigger Role

Ali Shamkhani was replaced as Iran's top security official after almost 10 years in the position.
No official reason was given for Shamkhani's departure, but he may be considered for a more significant role in the Iranian government.
Shamkhani's replacement is former Revolutionary Guards general and hardliner Ali Akbar Ahmadian.
Shamkhani successfully improved Iran's relations with Saudi Arabia and other Gulf nations.
The leadership change is not expected to impact Iran's security policies.
