Troops sent to quell clashes over land rights in northeast India killed five people Tuesday after the government ordered them to shoot suspects on sight. The killings and the discoveries of more bodies raised the toll from the violence in Assam State to 32 since Friday, according to G. D. Tripathy, the Assam home secretary. An additional 170,000 people have fled to more than 100 relief camps to avoid the fighting between the ethnic Bodo and Muslim settlers, who are mostly Bengali, in the western district of Kokrajhar. The police have found 27 bodies, most of them hacked with machetes and left in the jungle or beside roads or rivers. About 80 homes were burned down overnight as the violence spread to the neighboring Dhubri and Chirang districts. Residents of the village of Dimol fled Tuesday. Authorities sent about 5,000 army and paramilitary troops to the region with a mandate to shoot people suspected of arson and rioting on sight, said the Assam chief minister, Tarun Gogoi. Animosity and accusations of land theft have long simmered between Bodos and the settlers, who have clashed sporadically since the 1990s and burned each other’s homes and property.
