Protests erupted in Mashhad's Sayyad Shirazi neighborhood near Imam Hossein Mosque, where crowds gathered to mark the 40th day since demonstrators were killed in earlier waves of anti-government unrest.
Authorities have reportedly deployed heavy security presence and shut down internet access to conceal the scale of the disturbances.
An X post shared a video purportedly showing regime forces (referred to as "thugs" and Basijis) marching through streets, opening fire on civilians, with one yelling "DON'T FILM!"
