Dozens of firefighters have been battling with a major fire in Gloucestershire overnight.
About 40 firefighters were sent to deal with the fire "at a commercial premises" in London Road, Stroud.
An investigation into the cause of the fire is under way.
A spokesman for Gloucestershire Fire and Rescue said: “We were called at around 7.30pm yesterday evening by a member of the public informing us of a fire at commercial premises on the London Road in Stroud.”
“The fire is now mostly out. One engine remains at the scene damping down. No persons were involved in the incident. The cause of the fire is currently unknown and under investigation.”
Police sealed off roads in order to allow the nine teams of firefighters to battle the blaze which broke out near Stroud last night.
Witnesses told Gloucestershire Live the fire appeared to be at the Stafford Mill estate near Thrupp with unconfirmed reports that a car repair shop was involved.
Gloucestershire Constabulary confirmed they were called to the scene to close the surrounding roads.
The main A419 is said to have been closed amid reports of heavy, acrid smoke in the area.
The road has been closed near the Ship pub in Brimscombe and the fire service is using an aerial platform to help douse the flames.
Last night, Ian Tonner, area manager at Gloucestershire Fire and Rescue Service, said: “We were called at around 7.30pm this evening by a member of the public informing us of a fire at commercial premises on the London Road in Stroud.
