Two people have been taken to hospital after a gas explosion at a terraced house in east London.
Footage on social media showed the moment of the blast on a residential street in Ilford – which caused a fire that significantly damaged the roof, both of its floors and the loft conversion.
The house had been converted into flats, the London Fire Brigade said.
Some 60 firefighters were sent to tackle the blaze on Ley Street and two people were rescued from a first-floor window using a ladder. They were taken to hospital by the London Ambulance Service.
Two neighbouring properties are being assessed by a dangerous structures engineer, the London Fire Brigade said.
Emergency services took the first calls about the fire at 4.09pm and it was brought under control by 6.23pm. Crews will remain on the scene throughout the evening.

“We treated three people. We took two to hospital and discharged a third at the scene,” they added.
The London Fire Brigade said the cause of the explosion was being investigated.
