A multitude of heads of state and government officials are set to convene in Tehran for the state funeral of former Iranian Supreme Leader Ayatollah Ali Khamenei, who was killed in a joint US-Israeli air strike on February 28. The seven-day commemoration, starting on Friday, is expected to attract representatives from over 100 countries, marking one of the largest public funerals in modern history. The funeral procession will traverse various cities, including Tehran, Qom, Najaf, and Karbala, before culminating at the shrine of Imam Reza in Mashhad on Friday. Notable foreign leaders are expected to attend the ceremony on Friday, followed by public ceremonies in Tehran on Saturday and Sunday. The funeral processions will then proceed towards Qom on Monday and Tuesday. In light of Israel's recent threat to assassinate Khamenei's son, Mojtaba Khamenei, he will not be attending the funeral due to security concerns. Iranian military commanders have issued a stern warning to the US and Israel against any aggression during the state funeral, threatening harsh retaliation.
