Sanjana (7), Priya (5) and Roshni were having their food when the house roof suddenly collapsed on them here yesterday, they said.
On hearing their cries, the locals ran and took the girls out of the debris. Sanjana and Roshni died on the spot while Priya was admitted to a hospital in Sarsaul in critical condition.
She was later taken to Kanpur for treatment where her condition is still serious. Investigations are on in the matter, police said.
