Following the death of former Iranian Supreme Leader Ayatollah Ali Khamenei in February due to US-Israeli strikes, a multi-day public mourning and funeral procession has commenced in Tehran, with his body lying in state at the Grand Mosalla starting Friday. The events, dubbed the "funeral of the century," are expected to draw 12 to 20 million attendees ahead of his burial in Mashhad next Thursday. The Iranian government has ordered the closure of public and private offices in Tehran from Saturday through Monday and implemented traffic restrictions in the city center, with airspace over Tehran partially closing on Friday and fully closing on Monday. The ceremonies will move to Qom, Najaf (Iraq), and Karbala before Khamenei's burial in Mashhad. Representatives from multiple countries, including Pakistan's Prime Minister Shehbaz Sharif, are expected to attend the ceremonies. The funeral proceedings, lasting six days, aim to commemorate Khamenei's life and influence across the Shia Muslim world while showcasing Iran's religious and political ties in the region. Key questions surround whether Khamenei's successor and son, Mojtaba, will attend the funeral, as well as who will lead the funeral prayer, a position that carries both religious and political significance in Shia tradition.
