The body of Ayatollah Ali Khamenei lay in state in a vast hall in Tehran on Friday as clerics, officials, foreign dignitaries and other mourners paid their respects to Iran’s late Supreme Leader, slain by US and Israeli bombs. Iran is staging a week of mass funeral processions for Khamenei, whose 37-year reign was brought to an end in February by the first airstrike of the war, in a show of public devotion to the Islamic Republic’s theocratic state and revolutionary zeal.
