Shia Muslims across the world took part in processions, on Sunday, prior to observing Ashura. As part of the procession, they took part in self-flagellations and walked on burning coals.

Ashura, a 10-day-long event, commemorates the death of Prophet Mohammad's grandson, Imam Hussein, who was killed in the 7thcentury battle of Kerbala.

Shia Muslims have, for the past 1,300 years, been following the ritual of hurting themselves during Ashura, which falls on the 10th day of the first month of Muharram (month of mourning) in Islamic calendar. This year, Ashura falls on Dec. 6.

The followers, including Muslim women, even re-enacted the battle of Kerbala during the mourning process, across Lebanon, Pakistan, Afghanistan and other Islamic nations.
