'Cigarette caused' fatal Derby house fire
A house fire which killed an elderly woman was caused by a cigarette that was not fully put out, the fire service said.
The 78-year-old, who has not been named, died in the blaze on Mundy Street, in Derby, on Monday morning.
A Derbyshire Fire and Rescue Service investigation concluded the most likely cause of the blaze was accidental due to "smoking materials".
A man was also taken to hospital for minor burns and smoke inhalation.
The fire service said it believed the blaze started in a bedroom.
It has now urged smokers to ensure their cigarettes are fully extinguished and never to smoke while in bed.
Firefighters managed to stop the blaze from spreading to neighbouring houses.
