A mentally unstable woman strangled her two children to death in the Balur Math area of Madaripur city on Wednesday afternoon.
AHM Salauddin, officer-in-charge (OC) of Madaripur Sadar Model Police Station, confirmed the matter.
The deceased were Jannat (3) and Meheraj (1).
The mother, Tahmina Akhter, has been taken into police custody, and the bodies of the two children were sent to the Sadar Hospital for autopsy, the OC said.
According to locals, after a dispute with her husband, Abdul Halim, Tahmina moved back to her father's house with the children and had been undergoing treatment for mental instability.
In the afternoon, when Tahmina's mother went to the roof of the house to dry clothes, she locked the door of her room and strangled the two children.
Family members tried to open the door but failed, prompting them to call the police. Later, a police team went to the house, broke down the door, and found Tahmina sitting with the bodies of two children.
