Firefighters from Elland helped to tackle a huge blaze on the outskirts of Bradford city centre.
The fire, which started at 11.36am, was centred on industrial units on Thornton Road in the Listerhills area, one of the main routes into the city centre.
Plumes of smoke could be seen across the city as eight crews raced to the scene.
Police cordoned off the area around Thornton Road and Listerhills Road, with traffic congestion in the area.
West Yorkshire Fire Service said the fire started in an industrial unit containing cars, on Norcroft Street off Thornton Road.
The unit is part of a larger complex measuring 70 by 50 metres. Some smaller units may also have been affected.
The fire was extinguished using six large jets, one aerial jet, two ground monitors and two breathing apparatus sets.
Appliances from Elland, Odsal, Bradford, Fairweather Green, Idle, Cleckheaton, Bingley Stanningley, Rawdon, Leeds, Mirfeild and Castleford attended, along with other specialist appliances.
A West Yorkshire Fire and Rescue Service spokeswoman said there were no reports of any injuries.
