Four fire engines and around 25 firefighters tackled a fire at a residential block of flats on Banning Street in Greenwich.
A bin room on the ground floor of the six-storey building was damaged by fire. Around 40 residents left the building before the arrival of the Brigade, and one adult woman and three children suffering from smoke inhalation were taken to hospital by London Ambulance Service.
The Brigade was called at 1835 and the fire was under control by 2040. Crews from
East Greenwich, Greenwich and Deptford fire stations attended the scene.
The fire is believed to be accidental and the cause is under investigation.
