Police in Nairobi have launched investigations after a mother on Wednesday night committed suicide in Komarock estate, after poisoning her two children.

In a police statement, police said they found a suicide note in the woman's bedroom in which she claimed she was tired of being mistreated by her husband.

Her husband told the police that they had an altercation and hadn't talked with each other for almost a day.

Police are yet to establish what kind of poison the woman administered to her children.

The scene of the crime was visited by Kayole police officers who found the remainder of the poisonous solution in the kitchen.
