A senior police officer said the assailants were armed with sophisticated weapons. They pulled people out of their houses and shot them dead in cold blood, he added.
The victims belonged a backward caste.
The killing of two children of an upper caste earlier in the day at Kashichak village was suspected to be the provocation for the attack, the police officer said.

Superintendent of Police Baldev Prasad has rushed to the spot with additional forces.
