Three children and an adult had to be rescued during a seventh-storey flat fire in Cardiff.
The blaze happened in a residential apartment above the Park Plaza Hotel, but the rest of the building had to be evacuated.
Ten fire engines and specialist appliances went to the scene after the callout shortly after 01:00 BST.
Those rescued were taken to hospital but were not seriously hurt, the Welsh Ambulance Service said.
The cause of the fire, in Greyfriars Road, is under investigation.
South Wales Fire and Rescue Service said the blaze was contained within the flat, which has been severely damaged.
It is understood the hotel occupies the first four floors of the building, with flats on floors five to seven.
South Wales Police said local residents were moved to safety and officers asked the public to avoid the area during the incident.
The fire service said the incident was declared over just after 05:00.
The ambulance service said the four casualties were taken to the city's University Hospital of Wales at about 02:30.
Park Plaza general manager Margaret Waters praised emergency service personnel, who did a "wonderful job", along with staff who evacuated all guests.
