Solemn funeral observances for Iran's Supreme Leader Ayatollah Ali Khamenei are set to begin, drawing an estimated 15 to 20 million mourners. Iran issued a stern warning to the United States and Israel against any miscalculations during this sensitive period. Funeral events are planned to extend until July 9, culminating in Khamenei's burial in his hometown, Mashhad. Regional government delegations have started arriving in Tehran to pay their respects. Notably, Saudi Arabia's Deputy Foreign Minister made an unexpected appearance, signaling a potential thaw in Gulf-Iran relations. The U.S. administration is reportedly holding off on further military actions, coinciding with American Independence Day celebrations. Russia's delegation, led by Dmitry Medvedev, also arrived to honor the late leader. Iranian President Masoud Pezeshkian, accompanied by other officials, prayed before Khamenei's coffin. Media reports indicate that Khamenei's body has arrived at Tehran's Grand Mosalla mosque, with a red flag from a shrine placed over his coffin. Brigadier General Ahmad Vahidi, the new IRGC commander, made a rare public appearance at a memorial event.
