About 80 firefighters are tackling a fire at a block of flats in Battersea, south-west London.
The entire top floor and roof of the four-storey residential building on Maysoule Road is alight, London Brigade (LFB) says.
Firefighters are using a 105ft (32-metre) turntable ladder as a water tower to help tackle the flames from above.
The building has been evacuated by fire crews wearing breathing apparatus, although it is not known whether anybody has been injured. The cause of the fire is not known at this stage.
