Ashura, one of the most significant religious events for Shiite Muslims, was observed across Iran with large public gatherings.
Main ceremonies took place in major cities including Tehran, Mashhad and Isfahan. In the capital Tehran, thousands gathered at mosques and central squares to take part in commemorative rites, including Quran recitations, processions and sermons on the meaning of the event.
Ashura marks the martyrdom of Imam Hussein, the grandson of the Prophet Muhammad, at the Battle of Karbala in 680 AD. The event symbolizes sacrifice and resistance against injustice in Shiite Islamic faith.
During the day, many Iranians dressed in black and engaged in charitable activities, distributing food and water to attendees. Security measures were heightened to ensure the safety of the ceremonies.
Iranian authorities said the commemorations proceeded in a solemn and peaceful atmosphere, with participation from all walks of life, from the elderly to children.
