Massive crowds gathered at Tehran's Grand Mosalla mosque complex on Saturday for the state funeral of the late Supreme Leader Ayatollah Ali Khamenei [1].

The ceremonies mark a pivotal transition for the Iranian state, as the death of the Supreme Leader creates a vacuum in the country's highest religious and political office.

Funeral proceedings began Saturday [2], with the body of the leader lying in state to allow the public to pay their respects [3]. Authorities said that the body will remain in state until Monday [4].

Reports on the size of the crowds vary. Some sources said the gathering consisted of thousands of people [5], while others reported tens of thousands of mourners [1]. The Globe and Mail reported that hundreds of thousands of mourners began the daylong funeral [2].

The Grand Mosalla complex served as the primary site for the mourning rituals. Iranian authorities said the funeral will serve as a rallying point for national unity during the transition period [2].

The scale of the public response is being closely monitored by international observers. The events in Tehran reflect the state's effort to maintain stability while honoring the late leader's legacy through mass public mourning [3].

The body will lie in state until Monday

The death of Ayatollah Ali Khamenei triggers a complex succession process within Iran's clerical establishment. By organizing a large-scale state funeral and encouraging mass public mourning, the Iranian government seeks to project an image of continuity and national cohesion to prevent internal instability or external opportunistic pressure during the leadership transition.
