A block of flats in Leicester was evacuated after a discarded cigarette sparked a fire in a first floor apartment.
Emergency services were called to Abbey Park Street, in Belgrave, just before 9pm on Friday.
Several people were treated for smoke inhalation and some taken to Leicester Royal Infirmary as a precaution, however, a fire service spokesman said no-one was seriously hurt.
Crews from four stations attended the incident after the alarm was raised by a tenant.
A fire service spokeswoman said: "We were called to a fire in a first floor flat, however, on arrival, crews discovered it had spread to a second flat.
"The building was evacuated by firefighters and police but no-one had to be rescued."
She said crews entered the building using breathing gear and a jet was trained on the blaze from an aerial ladder platform.
"Everyone was accounted for but a few people were treated for smoke inhalation," she said.
"Some occupants were taken to hospital as a precaution."
The fire service could not say how many people were in the flats at the time but said the blaze was extinguished and stop message received from crews at 11.23pm.
The spokeswoman said the fire started in a bedroom and was caused by a discarded cigarette.
The bedroom was gutted in the blaze, with smoke and fire damage to the remainder of the property.
Most residents were able to return to their homes.
