Four people were killed Monday when police allegedly fired at mobs of Hindus and Muslims on a rampage in a western Indian city after authorities demolished a small Islamic shrine. Residents in the Fatehpur area of Vadodara (formerly known as Baroda) in Gujarat state blamed the deaths on police whom they said used bullets and tear gas. But police said firearms used by rioters hit them. A curfew was imposed in the city as the sectarian riots led to looting, police said. At least 10 other people were injured by gunfire from the police or bricks hurled by rioters, police said. The riot was sparked after the Vadodara Municipal Corporation (VMC) began to demolish a Muslim dargah, or shrine near a landmark city gate, witnesses said. "We offered to remove it ourselves but the VMC officials chose to demolish the dargah, raze it to the ground and build a road over it."
