A Nigerian family has been thrown into mourning after a mother accidentally caused the death of her four-year-old twin sons while trying to rid her home of a rodent infestation.

The incident was shared online by Nigerian businesswoman Chioma Ifeanyi-Eze, who revealed that the grieving woman works as her mother's house cleaner.

According to Ifeanyi-Eze's social media post, the mother had laced pieces of bread with rat poison and placed them in a hidden area of her home to catch rats. Unaware of the danger, one of the four-year-old twins discovered the poisoned bread, ate part of it, and shared the rest with his twin brother. Both boys subsequently died from the ingestion.

"The woman who cleans my mum's house lost her set of 4-year old twin boys," Ifeanyi-Eze wrote. "She put rat poison on bread and dropped on the floor in a hidden area. One of the twin found the bread, ate and give his brother. Both, passed."

She described the mother as a dedicated worker who was previously raising five children before losing two in a single day to the tragic accident.
