An elderly man has been injured in a gas explosion at a house in Dorset.
Windows were blown out and part of the roof destroyed at the terraced house in the Fortuneswell area of Portland at about 10:30 GMT.
The uphill section of the A354 Fortuneswell one-way system was closed but has since reopened.
Dorset Fire & Rescue Service said crews had isolated the gas supply and requested structural engineers to assess whether the building was safe.
The injured man, thought to be about 80 years old, was taken to Dorset County Hospital.
