The deceased were identified as Oichon Bewa, wife of late Jamir Uddin of Burasardubi village.
According to locals, the blanket of Oichon caught fire apparently from a kerosene lamp and she couldn’t escape due to her old age.
Later locals brought the fire under control.
Hatibandha Police Station Officer-in-Charge (OC) Mahmudunnabi said police were sent to the scene for investigation.
