Iranians from all walks of life will participate in mourning rituals in all the cities and towns of the country to mark Ashura Day.

Ashura is the 10th day of Muharram. In 61 AH (October 10, 680 CE), Imam Hussein (AS) and his faithful companions were martyred in the battle against the Kufa army led by 'Umar b. Sa'd. This day is significant for Shia due to what occurred in Karbala on this day.
