Firefighters have issued a candle warning after a flat fire on Amsterdam Road in Cubitt Town.
Part of a three-roomed flat on the ground floor of a residential block was damaged by fire. A man and two women left the building before the Brigade arrived and were treated on scene by London Ambulance Service crews.
The fire is believed to have involved a candle.
A London Fire Brigade spokesperson said: "Candles are one of the most common causes of fires in the home and you should be careful when using them.
“It’s really important that you never leave them unattended and keep them away from anything that could catch fire such as curtains, furniture or clothes.
"We recommend swapping traditional candles for LED flameless ones as they are much safer, but if you do use real candles, follow our simple safety tips."
The Brigade was called at 0157 and the fire was under control by 0242. Four fire engines and around 25 firefighters from Millwall, Poplar, Plaistow and Dowgate fire stations attended the scene.
