Authorities now report turnout estimates of 15–30M across the six-day procession and have expanded security, checkpoints, transport and relief stations to manage extreme heat and persistent crowding.The procession began at the Imam Khomeini Grand Mosalla in Tehran and will move to Qom, Najaf, Kerbala and Mashhad, with coffins of Ali Khamenei and several family members displayed throughout and Mojtaba Khamenei remaining out of public view.The ceremonies blend religious ritual and political messaging—chanting for revenge and provocative social media posts—and analysts warn the mass mobilization could both consolidate and expose fractures in
Iran’s political order while complicating US-
Iran diplomatic talks.
