DUBAI, July 2 - Iran's ruling clerics are preparing days of mass funeral rites for Ayatollah Ali Khamenei as a show of public devotion to the Islamic Republic and proof that its revolutionary fervor still burns strong.
Iran's supreme leader was killed by U.S. and Israeli strikes in their first attack of the war and the funeral events will begin over the weekend in Tehran, with mass processions planned next week in Qom and Mashhad and ceremonies in Iraq.
