Residents at Kandalo village on the outskirts of Kisumu town were left in shock after a woman killed herself and her two children.
Neighbours said the woman called her two children to their house at around 10am, tied their hands with ropes, and doused them with petrol before she set the house on fire.
The area chief Simon Osego said some neighbours had spotted the woman purchasing petrol at a nearby fuel station.
Neighbours said they heard muffled screams of the children from the burning house, however they could not rescue them since the door was locked from inside.
Rukia Anyango and her children, identified as Shalin Wasuna, 8, and Osman Wasuna, 2, were burnt beyond recognition.
The horrible incident was linked to a domestic squabble between Anyango and her husband.
Police retrieved the charred bodies and took them to a mortuary in Kisumu.
