Ayatollah Ali Khamenei, who ruled Iran as supreme leader for 37 years, was killed on February 28 in U.S. and Israeli airstrikes according to multiple reports. His son Ayatollah Mojtaba Khamenei succeeded him, with funeral ceremonies held at the Imam Khomeini Grand Mosalla mosque in Tehran featuring five caskets including one for a 1-year-old granddaughter. Attendance figures, ceremony start dates, and certain chants remain disputed across sources.
