Around 100 firefighters are tackling a fire in a 17-storey block of flats in south-east London.
A flat on the 15th floor of the tower in St Mark’s Square, Bromley is on fire as well as part of the roof, the London Fire Brigade (LFB) said.
The cause of the blaze is unknown.
Footage posted on social media showed flames and black smoke coming from one part of a slanted roof.
Station Commander Colin Digby, at the scene, he said: “Crews are making steady progress. This is going to be a protracted incident and we expect our crews to be on scene for several hours to come.”
Firefighters were called just before midday and remain at the scene.
Fire crews have been using a 64-metre turntable ladder to tackle the fire, which has been seen pouring smoke into the air.
Teams from Bromley, Beckenham, Addington, Woodside, Lewisham, Forest Hill, Sidcup and Croydon and surrounding fire stations have been involved in tackling the flames.
Josh Gill, 29, a Co-op team leader from Bromley, said: “I literally live on the doorstep.
“I was in my flat and my mother-in-law came over to pick up my wife’s niece who stayed over last night, and as she came she said about the fire and saw all the fire brigade appear and (I) went to have a look.
“Some people were upset and crying whilst others were shocked and confused as to what was going on. The fire brigade are still here and you can see people who live in the flats evacuated in the church.”
“It is scary to see this right on the doorstep as I have a family.”
