Thousands of Shia Muslims were seen taking part in the sacred Shia Muslim ritual of Arbaeen, using knives to cut their heads in Mumbai on Sunday.

People were seen performing a self-flagellation ritual, continuing cutting their heads with knives despite being covered in blood, with some seen lacking hair in places of cuts, offering their sacrifice to the Holy Prophet's family.

The event, also known as Chehelom, marks the 40th day of mourning following the killing of the Prophet Muhammad's grandson Imam Hussein in the desert of Karbala, a date celebrated for more than 1,400 years.
