A huge blaze has broken out in west London. Ten fire engines and 72 firefighters are involved in tackling a house fire on Gloucester Square in Bayswater. The flames roared through the second floor and roof.

It is unclear what started the fire on Sussex Place near Paddington, but London Fire Brigade said that four people had left the property before they arrived. "Four adults left the property – a terraced house of three floors – before the arrival of the Brigade and there are no reports of any injuries," it said in a statement. "Part of the second floor and part of the mansard roof is alight."

There are no reported injuries. Emergency services were called at 5.30pm GMT.

Local resident Francois Julien told the Evening Standard: "At around 5.30 I noticed a smell of smoke in the air. At the beginning it was huge. There were three windows on fire." He added: "I just hoped there was no one inside because it was burning like crazy."

Station manager John Ryan said: "Crews are fighting the fire from both sides of the property as well as using aerial appliances to tackle the blaze from above. Firefighters are working hard in challenging conditions to bring the fire under control."

He added: "Fire engines from Paddington, Kensington, Euston, Soho, West Hampstead, Lambeth, Hammersmith and North Kensington fire stations are at the scene.

"The cause of the fire is not known at this stage."
