Iran began state funeral ceremonies for former Supreme Leader Ayatollah Ali Khamenei on Saturday after a second day of national mourning [1, 2].

The event marks a critical transition for the Islamic Republic as it navigates the loss of its highest authority amid ongoing regional instability. The ceremonies serve as both a religious rite and a demonstration of state continuity.

Main ceremonies are taking place in Tehran, where the body is lying in state and prayers are being held over the casket [3, 4]. Additional rites are planned for the cities of Qom, Najaf, Karbala, and Mashhad [5].

Crowd estimates vary across reports. Some sources said that hundreds of thousands of mourners have gathered [2], while others expect millions to attend in Tehran [6].

The funeral is described as either a six-day [7] or week-long event [3]. The proceedings include the attendance of Khamenei's sons, President Pezeshkian, and other top government officials [1, 2].

Reports on the cause of death differ. Some records said Khamenei was killed in war [8], while other reports said his death occurred four months prior to the funeral ceremonies [5, 1].

Security remains tight across the capital. Some reports said that up to 3,000 deaths are expected during the funeral period [6].

Main ceremonies are taking place in Tehran, where the body is lying in state.

The scale and duration of the funeral ceremonies reflect the Iranian government's effort to legitimize the succession process and maintain internal stability. By extending the rites across multiple holy cities and utilizing a week-long period of mourning, the state is attempting to consolidate public loyalty and project strength during a period of leadership transition and external conflict.
