At least 70 firefighters tackling massive blaze in Tottenham, London
At least 70 firefighters are at the scene
A further 60 firefighters are said to be battling another huge fire at a recyling plant in west London, on a busy bank holiday for the London Fire Brigade.
The first fire broke out at what is believed to be a row of disused warehouses in Bernard Road, NW15.
Video footage shows huge flames ripping through the top of the building, as white smoke billows out from under the corrugated roof.
One witness said there were at least 10 fire engines and an ariel platform spraying water onto the blaze from above.
The man, who did not want to be named, said it looked like the blaze was being brought under control until a fresh wave of smoke began to rise from the building.
