Several residents were taken to hospital suffering from severe burns, as well as fractured bones after leaping onto the street.
In a separate fire on Thursday morning, at least four people died in an intensive care ward in a hospital in Muzaffarpur in the eastern state of Bihar, district government official Subrat Kumar Sen said.
