The Muslims were taking part in processions in Mumbai and Chennai. Ashura is celebrated on the tenth day of the Islamic month of Muharram.
The processions also involve walking on burning coals and carrying a 'Tazia' - replica of the coffin of Hussein.
Some participants gather for ceremonial chest beating as a display of their devotion in remembrance of his suffering and to preach that oppression will not last.
In some Shi'a regions of Muslim countries such as Afghanistan, Iran, Iraq, Turkey, Azerbaijan, Pakistan, Lebanon, and Bahrain, the commemoration has become a national holiday.
Most ethnic and religious communities participate even in a predominantly Hindu majority.
