Over a hundred firefighters are tackling a huge fire that has broken out in a warehouse in Tottenham, North London.
20 fire engines are being used to deal with the blaze on White Hart Lane.
A London fire brigade spokeswoman said warehouse storage units were alight and officers were still trying to determine the cause of the fire on Monday.
She said: "Twenty fire engines and around 120 firefighters have been called to a fire at a warehouse on White Hart Lane in Tottenham.
"Warehouse storage units are alight. The brigade was called at 20.17 and is still at the scene.
"Firefighters from Tottenham, Hornsey, Edmonton and the surrounding fire stations are at the scene.
She added: "The cause of the fire is not known at this stage."
Twitter users have uploaded videos showing the building engulfed by flames, and plumes of black smoke are visible across large parts of north London.
Local resident Alex C described the fire as "absolutely terrifying", particularly for those living directly opposite the warehouse which collapsed as the fire took hold.
London Ambulance Service said one patient had been taken to hospital with burns to the hand.
A spokesman said: "We were called just before 8pm.
"We sent two ambulance crews, an officer and members of our hazardous area response team to the scene.
"One patient has been treated and taken to hospital with burns to the hand and we remain on stand-by at the scene."
The injuries are not thought to be serious, he added.
Local residents were not told to leave their homes, despite the proximity of the fire to some houses.
London Fire Brigade station manager Sam Kazmanli said: "This is a large fire, cylinders are involved so a hazard zone has been set as cylinders can explode when exposed to heat.
"There is a lot of smoke in the air. As a precaution, local residents are advised to keep their windows and doors closed."
