At least 32 people from the minority Muslim community have been killed by the suspected Bodo rebels in two days of violence in India's northeastern Assam state.
The attackers sprayed bullets on people before setting more than 40 houses on fire. Thousands of people have fled their homes for safety.
Relatives of victims, who refused to bury their dead, finally performed the last rites on Sunday after the government promised to punish the culprits and provide security.
At least three rebels have been killed by the army, which has been deployed in the region following the killings.
In similar attacks nearly two years ago, Bodo rebels killed about 100 people and forced more than 400,000 people to flee their homes.
