Arson suspected in Oxfordshire council blaze
Oxfordshire Fire and Rescue Service have said they are using 13 fire engines to battle a blaze at council offices on Benson Lane in Crowmarsh Gifford.
The South Oxfordshire District Council building has been ablaze since 03:15 GMT.
Council leader John Cotton told the BBC: "We believe it to be the result of arson, though that's not clear at the moment."
Firefighters are also dealing with two other fires in the area.
Eyewitness Karl Mitchell-Shead told the BBC's Annita McVeigh that he saw a burnt-out vehicle in the foyer of the council building.
