Factbox-Who is Iran's Mohsen Rezaei, the hardliner appointed to key security role?

Iran has appointed Mohsen Rezaei as secretary of its Supreme National Security Council, elevating a prominent hardliner and close ally of new Supreme Leader Mojtaba Khamenei amid the months‑long conflict with the United States.
Rezaei, 71, is a longtime revolutionary and IRGC veteran who became commander at 27, led the force through much of the Iran‑Iraq war, and later held senior political and economic posts.
He’s known for provocative, anti‑negotiation rhetoric (including saying a U.S. ground invasion would let Iran take “thousands of hostages”) and remains a controversial figure because of disputed wartime operations like Karbala‑4.
