At least two people have died and 17 others have been injured after a three-storey building collapsed into a construction site in Brooklyn, New York.
The incident happened in the borough’s Flatbush neighbourhood, bringing down part of the structure alongside an excavation site.
Four people have been hospitalised in a critical condition, while emergency crews continue searching through the rubble for anyone who may still be trapped.
Firefighters have been digging through tonnes of bricks, timber and debris after the building collapsed shortly after four o’clock local time.
The three-storey structure stood alongside an excavation site where another building had been demolished.
The collapse sent debris crashing into the construction pit and exposed rooms in an adjoining residential building. Emergency crews have used rescue dogs, drones and cutting equipment to search for the survivors.
New York’s Department of Buildings has deployed inspectors to assess the structural stability of neighbouring properties.
Authorities have not established what caused the collapse, amid a sizable rescue operation.
