At least nine people have been killed in the Indian state of Rajasthan when two communities clashed over a piece of land, police said. Members of the low-caste Gujjar and Muslim communities opened fire and pelted each other with stones on Wednesday in Bharatpur town, famous for its bird sanctuary, the BBC reported Thursday. Both communities claim ownership of a graveyard and a court case is going on. Officials said a curfew had been imposed in parts of the district. More than a dozen people, including some policemen, were injured in the clashes. Reports quoting witnesses said several shops had been set on fire. Additional forces have been deployed and the situation is now under control, police said.
