Millions of Iranians have started an eight-day period of mourning for the country’s former supreme leader after he is reported to have been slain, according to multiple Australian outlets. The reporting describes the mourning as a nationwide observance that begins immediately and continues for eight days. The sources are consistent in stating the scale of public participation, referring to “millions” of people taking part in the mourning period. They also agree on the central subject of the tribute: the former Iranian supreme leader, whose death is described as a killing. Beyond the initiation of the mourning and its duration, the provided excerpts do not add further verified details about the circumstances of his death, any official government statements, or the specific public ceremonies planned during the observance. All three outlets present the same core information: that the mourning period has begun and that it lasts eight days, with broad public involvement across Iran.
