Iran has announced a multi-city funeral procession for Supreme Leader Ayatollah Ali Khamenei, who died Friday at the age of 83. The funeral will begin in Tehran and proceed through several major cities, allowing citizens to pay their respects. State television broadcasts are dedicated to coverage of the event, and flags are flying at half-mast across the country. A period of national mourning has been declared, with government offices closed for several days. Details regarding the selection of a new Supreme Leader have not yet been released, though the Assembly of Experts is responsible for choosing his successor. The funeral is expected to be a significant display of national mourning and political unity. Khamenei had held the position of Supreme Leader since 1989, wielding considerable power over Iran’s political and religious affairs.
