A workman has reportedly been pulled from the rubble of a building after it came crashing down into the road.
The dramatic collapse took place on a quiet residential street in Welling, south east London, this afternoon.
The property was surrounded with scaffolding and workmen were in the process of demolishing it when it collapsed.
A man was rushed to hospital and a safety cordon has been set up at the scene.
One witness told The Sun: “It looks like people were working on it today.
“I saw one of the workmen being carried out by his colleagues.
“The wall has basically fallen out onto the pavement on one side of the street.”
Firefighters were called to the property at the junction of Central Avenue and Wickham Street at around 1.18pm.
Crews left the scene at shortly after 2.20pm.
It comes after seven people were injured in a house explosion in Ashford in May.
Shocking footage showed the aftermath of blast, which took place at around 7.57am.
Neighbour Jay Weston, 52, who took the video, said: “I was about to go out my front door and I thought something was coming crashing through my ceiling.
“Twenty minutes later and there would have been school children walking along that road.”
A woman who was rescued from the home was 100-years-old, a neighbour said.
Seven people were injured – two of them seriously – and police confirmed no-one was missing following the blast at a home occupied by an elderly couple.
Neighbours said the house was “completely gone” after they were startled by a “loud bang” and rushed outside to discover the inferno.
Dramatic aerial photos revealed the scale of the devastation, including the charred shell of the mid-terrace property that blew up, and heavy damage to two neighbouring homes.
The chimney of the affected property was the only part of the building which was still standing.
Of those injured, two were taken to hospital in London with serious injuries and five were taken to hospital in Ashford with “less serious” injuries. Some neighbouring homes were evacuated as firefighters tackled the blaze.
A neighbour told the Mirror: “We heard an enormous explosion and the house shook.
“We went running upstairs and saw the house across from us blown apart and the fire just starting up.
“We was straight on to the fire and emergency services. There was smoke and fire and debris everywhere.
“I’m pretty shaken up at the moment over the while situation, and just hoping they are ok.”
Meanwhile another house explosion left four adults and a child trapped after a building collapsed in Ealing, west London, last year.
The explosion reportedly occurred inside a phone shop, Dr Phone, leaving at least one man injured.
Shop owner Jatinder Singh, 36, said he received a phone call from a neighbour to tell him his mobile phone shop had been totally destroyed.
He told the Evening Standard : “It’s an absolute mess.”
Station Commander Alan Brand said: “Four adults and one child were rescued at the rear of the property by firefighters using a ladder.
“A further fourteen adults and two children self evacuated from surrounding properties. Specialist crews are searching the building for anyone else that may be involved.”
Footage from the scene showed a huge emergency response, with many saying the shop and some of the property above had been completely destroyed.
