Up to 20 firefighters were tackling a blaze at a building in Northamptonshire on Sunday afternoon trying to stop it spreading.
Northamptonshire Fire and Rescue Service said they were called to a single-storey outbuilding off the A425 Daventry road in Staverton at 4.30pm.
Speaking earlier, a spokesman for the service said they did not have details at this stage as to the exact nature of the building.
Five appliances were in attendance, he said, with crews travelling from Warwickshire and elsewhere in Northamptonshire.
Fire crews were trying to ensure that the blaze did not spread to nearby buildings, he added.
