Shiite boys strike themselves with chained blades as part of a self-flagellation ritual marking Ashura, Nov. 25, 2012, New Delhi, India. The religious festival of Ashura, which involves a ten-day mourning period starts with the first day of Muharram on the Islamic calendar, commemorates and mourns the seventh-century martyrdom of Prophet Muhammad's grandson Imam Hussein in the battle of Karbala.
