A large fire in Kingswood - where smoke could be seen across Bristol yesterday - is thought to be arson.
Crews from Kingswood, Yate, Hicks Gate, Patchway and Avonmouth fire stations were called to a fire involving around 300 containers on an industrial site.
Four firefighters in breathing apparatus used four 45mm jets and one high-pressure hose reel to extinguish the fire.
Firefighters also used chemical absorbent booms and environment agency pack booms to prevent chemical run off into nearby drainage.
The cause is thought to be deliberate.
