Mojtaba Khamenei has issued written messages and been referenced in official statements since his March 2026 selection as Supreme Leader by the Assembly of Experts, yet no authenticated live video, audio address, or public appearance has occurred as of late September. Iranian officials cite security risks tied to the February 2026 strikes that killed his father, while President Masoud Pezeshkian stated in a September 27 CBS interview that he held two recent meetings with Mojtaba—including one exceeding seven hours—and described him as fully healthy with no ongoing issues. A purported handwritten letter dated August 1 and released around September 22, plus an earlier undated short video clip, represent the main recent efforts to address proof-of-life concerns. Reports of internal discussions about potential succession changes after any U.S.-Iran agreement add further uncertainty around visibility timelines.
