Residents in Hackney have been urged to remain indoors and shut their windows after a fire sent clouds of black smoke into the sky.
More than a dozen fire engines and around 100 firefighters attended the scene after reports of “significant amounts of smoke” coming from a four-storey block of flats in Dalston, north east London.
One person was treated for smoke inhalation but no other injuries were reported, said the London Fire Brigade.
Some people were taken to a nearby church while firefighters tackled the fire.
Residents said the blaze was “devastating” for the community.
Rosie Speirs said the scene “was so horrible to see”.
She added: “The smoke was visible from all areas of Hackney and filled the surrounding streets with a dark fog.
