DUBAI, July 3 - The body of Iran's slain Supreme Leader Ayatollah Ali Khamenei was lying in state in a vast hall in Tehran on Friday as clerics, officials, foreign dignitaries and other mourners paid their respects after his 37-year rule.
Iran is staging a week of mass funeral processions for Khamenei — killed in February by U.S. and Israeli airstrikes at the start of a four-month war — in a show of public devotion to the Islamic Republic's theocratic state and revolutionary fire.
