Two men have been taken to hospital following a suspected gas explosion in a two-storey building in west London.
Emergency crews were called to flats at Carlyle House in Carlyle Road, South Ealing, at about 0915 GMT on Sunday after what one neighbour described as "a tremendous bang".
There was a strong smell of gas and debris has been scattered across the road, said a BBC reporter at the scene.
The men, in their 60s, suffered minor injuries, the ambulance service said.
Ten people were evacuated from the flats and the surrounding homes and were taken to Ealing Town Hall.
Everyone has been accounted for, London Fire Brigade said.
The building's roof and interior have been damaged and the block is considered unstable.
Tiles from the roof were lying in a children's playground and a park further along the street, BBC reporter Gareth Lloyd said, and the roof of the flat had been completely shattered.
Two crews and a "hazardous area" response team were among the ambulance units sent to the scene.
Additional emergency vehicles, including a fire command centre, arrived at about 1145 GMT.
South Ealing Road has reopened to cars but the 65 bus, which runs between Ealing and Kingston, remains on diversion.
Police said there was a risk the gas main in Carlyle Road could have been ruptured.
The road was likely to remain shut for most of Sunday as a result, they added.
