Iran opens a six-day state funeral for Ali Khamenei, expects 15M–20M mourners and enforces strict security and transport measures while Mohammad Bagher Ghalibaf urges revenge.The ceremonies follow strikes by the US and Israel that killed Ali Khamenei earlier this year, left Mojtaba Khamenei wounded and installed as supreme leader, and will include stops in Tehran, Qom, Najaf and Karbala before burial in Mashhad with foreign delegations attending.Officials present the events as a show of unity and Shiite ritual, vow a strong response to any renewed US or Israeli strikes, and face analysts' warnings about public discontent over sanctions, economic decline and repression.
