The victims were initially rushed to Maharishi Hospital from where they were shifted to the Lok Nayak Jai Prakash Hospital.
The police said Kamlesh's husband Suresh was not at home at the time of accident. Suresh works as a mason and the family belongs to Uttar Pradesh.
'Kamlesh in her statement before a sub-divisional magistrate said that there was a spark in the TV set and then the kerosene stove caught fire and suddenly everything was burning,' said a senior police officer.
Sanjay, Kamlesh's neighbour, said that they tried to help, asking the burning children to run out of the house but they were not even able to stand up.
'It was scary to see them, we kept splashing water but we could not save them,' Sanjay said.
The police said they have registered a case and are investigating the accident.
