Emergency crews say a man who was trapped inside a house that exploded in Hamilton has been pulled from the wreckage and taken to hospital.
Police say the man, whose name has not been released, suffered unknown injuries.
They say gas has been shut down near the home on Gibson Avenue, with about 200 homes affected.
Photos posted on Twitter appear to show a home with its bottom half destroyed, the roof intact but tilted forward and nearly touching the ground.
At least one car appears partially covered by the rubble.
It was not immediately known what caused the explosion.
