Iranian state television early Tuesday aired live images from a helicopter of hundreds of thousands of people walking toward Jamkaran Mosque, just south of Qom, for a funeral service for Khamenei. The mosque is believed by Shiites to have once hosted the Muhammad al-Mahdi, the 12th and last Shiite imam, who disappeared in the 9th century and will one day reappear to bring justice to the world.

Images of Khamenei and his son, Iran's new Supreme Leader Ayatollah Mojtaba Khamenei, were displayed on banners and posters held by mourners. Mojtaba Khamenei has yet to make an appearance in the funeral ceremonies, which are unfolding over several days. He is believed to be in hiding after reportedly being wounded in the airstrike that killed his father.
