The death of Iran's Supreme Leader Ayatollah Ali Khamenei has sparked a wave of emotion and tension in the region, with millions expected to attend the funeral processions. The atmosphere is electric, with mourners expressing both anguish and a desire for vengeance against the United States, which they accuse of having a "blood feud" with Iran. The security situation is tense, with Iran's Islamic Revolutionary Guard Corps warning against any attempts to target the country, and the US and Israel both expressing concerns about potential attacks. The funeral processions, which will take place across multiple locations in Iran and Iraq, are expected to be a massive display of grief and solidarity, with millions of people expected to turn out. The international community is also watching closely, with officials from China, India, and Pakistan among the foreign dignitaries attending. The funeral will last for several days, with the public part of the funeral beginning on Saturday at 6 a.m. local time, and the main funeral procession in Tehran expected to take place on July 6. The ceremony will be marked across five cities in two countries, with the body of Khamenei being transported to the Iraqi city of Najaf and then to the Imam Reza shrine in Mashhad, where he will be buried. The funeral is a significant event, not only for Iran but also for the region, and it will be closely watched by the international community for any signs of escalation or de-escalation in the tensions between Iran and the United States.
