One of the most iconic features of the Ashura Festival in Iran is the huge processions of mourners who march through the streets, chanting religious hymns and beating their chests in unison. These processions are often led by flag bearers carrying banners and symbols of Imam Hussein, followed by grieving men, women, and children who come together to express their sorrow and devotion to the martyrs of Karbala. In addition to the religious rituals and processions, the Ashura Festival also involves acts of charity and community service.
