A curfew has been imposed in a part of the northern Indian city of Lucknow after sectarian violence.
Lucknow has a history of sectarian clashes
Three people died and several were hurt when Shia and Sunni Muslims clashed at a Shia mourning procession in the Husainabad area on Sunday, police said.
Officials said that the curfew had been imposed to prevent further escalation of tension in the area.
Lucknow has a history of clashes between Shias and Sunnis over the mourning processions.
Officials told the Reuters news agency that rival groups threw stones, shot at each other and set vehicles and shops on fire after a dispute over the route of a Shia Muharam festival procession.
"Things are totally under control but we are maintaining a strict vigil in the areas where the clash took place," district administrator Aradhana Shukla said.
After recurrent clashes, Lucknow's Shias and Sunnis reached an agreement in 1998 over the limited number of mourning processions along specific routes.
