PHOTOS: Muslim world mourns on Muharram

On Tuesday, devout Shiite Muslims commemorated the martyrdom of the Prophet Muhammad’s grandson with mass flagellation ceremonies.

Known as Ashura, the ritual is celebrated on the 10th day of the Islamic month of Muharram (the first month of the lunar calendar).

It marks the death of Imam Hussein, the grandson of the Holy prophet in 680 AD in Karbala, near Baghdad in Iraq. He was killed by political rivals alongside an army of 72 men. Hussein's body was then mutilated, leading to his martydom.

As well as marking the occasion with self-flagellation - to emulate the suffering of Hussein - some take part in processions which involve walking on coals and carrying a ‘Tazia’ - a replica of his coffin.
