Parents of the children were not home when the fire broke out at the thatched roof of their hut yesterday, police said today.
Ashu and his one-year-old sister Vandana died in the blaze.
Both the children were alone when the thatched roof made up of dried grass came in contact with spark of fire from an earthen stove yesterday afternoon, police said, adding that their parents had gone to work in mines.
Fire fighters were called from the neighbouring Badi town, but it was all finished by the time the assistance reached, a police officer said.
