Firefighters have issued a smoking safety reminder after a fire at a block of flats in East Road, Hackney.
Four fire engines and 21 firefighters and officers were called to the fire. Part of a lower ground floor bin room was damaged by the fire.
The Brigade's 999 Control Operators took 18 calls to the fire.
Around 35 people were evacuated from the flats. Ten people were assessed on the scene by London Ambulance Service crews.
The Brigade’s fire investigators believe the cause of the fire was the careless disposal of smoking materials.
A London Fire Brigade spokesperson said: “Incidents like this show how important it is to ensure you always carefully dispose of cigarettes, matches and other smoking materials.
“When they are accidentally dropped or left to smoulder, they can cause serious fires.
“There are some simple safety tips you can follow to keep safe including not smoking inside, never smoking in bed, not leaving cigarettes unattended and using proper ashtrays which can’t tip over.”
The Brigade was called at 0847 and the fire was under control at 1008. Fire crews from Shoreditch, Islington, Whitechapel and Dowgate fire stations attended.
