More than 100 firefighters were called to set fires to south-east London, firefighters confirmed.
Twenty fire engines and 120 firefighters were battling a fire on the roof of a building on Creek Road, Deptford, on Tuesday afternoon.
London firefighters said they were called at 1.03pm, while videos showed large plumes of smoke emanating from the building at 4.15pm.
As of 10:30 p.m., a spokesperson for the Brigade told The Standard that six fire engines and 30 firefighters were still at the scene. Firefighters are expected to be on the scene overnight and into the morning, the spokesman said.
The cause of the fire remains unknown and no injuries have been reported at this time.
About 13 people evacuated the building before firefighters arrived to tackle the blaze.
Station Commander Ian Smith, who is at the scene, said on Tuesday afternoon: “This is an intense fire located in the roof of the building and fire crews are working hard in difficult conditions.
“We have increased the number of fire engines due to the need for more firefighters with breathing apparatus.
“There is a lot of smoke coming from the incident and we are asking local residents to close their doors and windows.”
In a tweet shortly after 6 p.m., the brigade said it was continuing to fight the blaze which it described as “complex and difficult”.
“Please close your doors and windows if you live in the area,” he added.
Michael Rudling, a resident of the building, told The Standard he encountered “thick black smoke” as he returned from his work experience to see the extent of the fire.
While his own apartment remains on the second floor, he said officials informed him that the top floor had been damaged due to the fire.
He added: “People were relatively quiet but it was typical London annoyance. People didn’t realize that firefighters worked hard and had to work hard to keep the cords in place.
