NEW DELHI, India (CNN) -- Authorities in India's remote northeastern state of Assam have deployed the Army to quell fighting between tribal people and Muslims that has left 34 dead and displaced more than 10,000.
The situation had improved by Monday in Assam's troubled Udalguri district, State Home Commissioner Rajiv Kumar Bora said.
The fighting started September 30. By Monday, 34 people have been killed, including 22 who were shot by police, said Assam's Police Inspector General B. J. Mahanta.
District authorities have set up 18 relief camps where more than 10,000 people are staying, he said.
The two groups have been clashing with bows, arrows and spears.
Police are investigating the cause of the flare up of the decades-old rivalry between the Bodo tribesmen and Muslims, who are seen as Bangladeshi settlers, Mahanta said.
