At least four people have been injured in a suspected gas explosion at a block of flats in south-west London.
Emergency services were called to Garratt Lane, Earlsfield, at 07:25 GMT over reports of a blast.
Local residents said they heard an “enormous bang” which “rocked” neighbouring houses and left debris strewn outside the damaged building.
London Fire Brigade (LFB) said a man in his 70s was rescued from the building and had been taken to hospital.
Another man from an adjacent flat was also taken to hospital while the Met Police said other people were treated at the scene for minor injuries.
One woman who lives close to the flat told the BBC she thought the “enormous bang… might have been a bomb or a train crash” after it “rocked” her house.
“It was so loud it almost threw me out of bed”, she said.
Sgt John Nicolaou said it was believed the explosion happened on the ground floor of the building.
“The Health and Safety Executive will be informed in due course and the gas board are at the scene now,” he said.
A 25m (82ft) cordon has been put in place around the three-storey block “as a precaution”, LFB said.
Garratt Lane has been closed at the junction of Burntwood Lane and motorists have been advised to avoid the area.
