Two minors died in a fire incident that was started by their mother in a house in Saina estate, Kajiado County.
The fire, which started Tuesday at around 2 pm, spread quickly burning down the iron sheet-made house.
The bodies of the two children aged 10 and two years were found after the fire had been contained, police said.
A love triangle is among the motives under probe over the incident, police said.
The woman was badly injured in the incident and was saved by neighbors who rushed her to hospital.
She cited differences with her husband as the reasons for the action of killing her children.
She was identified as Salome Williams.
Neighbors said she lit a gas cylinder and set off the fire as she and her children were in the house killing the two.
The remains of the two children were found in the house long after the fire had been contained.
Preliminary investigations point to the wife who was said to have had a domestic quarrel with the husband over the phone for the last two weeks, police said.
The husband is alleged to have been cohabiting with another woman and he has been away for the two last weeks.
He also called to quarrel with his wife.
Investigations into the incident are still ongoing, police said.
The remains were taken to a local mortuary pending autopsy.
