The battle to bring a dramatic warehouse blaze under control has entered its second day after it spread to a separate building which also went up in flames.
Firefighters had brought the fire at the first unit largely under control by midday, but pockets still remained unextinguished into Thursday night.
An adjacent warehouse has now caught fire as the flames spread and a fresh drive to bring it under control was launched with more crews sent to the scene at 10pm.
Shocking footage from the scene showed firefighters battling the blaze as smoke billowed into the night sky.
The initial fire broke out in the early hours of Thursday and crews were still at the scene on Friday morning.
Station manager Gary Norris said crews would remain at the scene overnight and urged people in the area to keep windows shut.
He said: “Due to structural damage it has been difficult for crews to gain access to the building.
“The fire has spread from units which were alight earlier today. Crews will remain on the scene throughout the night to continue tackling the fire, and extinguishing the deep seated pockets of fire in order to prevent it spreading any further.”
"There is a lot of smoke and we are reminding people to keep windows shut in the local area.”
In statement, London Fire Brigade said crews would remain at the scene throughout the day as they continue to tackle small deep seated pockets of fire.
Station Manager Lee Sandy confirmed the fire was now under control and was stopped from spreading any further.
The earlier blaze, which broke out in the early hours of Thursday, could be seen for miles across London.
Commuters shared images of thick, black clouds of smoke rising into the sky.
Witnesses as far away as Canary Wharf, about eight miles from the scene, reported seeing the smoke.
The cause of the fire was not immediately clear.
