A large fire has broken out at an industrial estate in Reading, leading to thick smoke billowing over parts of the town.
The blaze took hold in an office supplies recycling company in Stadium Way, Tilehurst shortly after 07:30 GMT.
Witnesses reported explosions and a huge plume of smoke. Train services were also disrupted while the fire was at its height.
Nearby residents were warned to stay indoors and close doors and windows.
Spokesman Paul Jones said 55 firefighters were tackling the "intense" blaze that was contained in one premises.
Polly Falconer, who lives nearby, said it was the "thickest, blackest smoke I've every seen".
Trains on the line between Reading and Didcot Parkway, which runs alongside the industrial estate, were delayed or cancelled for a time.
Reading Borough Council said the smoke plume was being blown towards the north east, in the direction of Caversham and Rivermead.
It warned motorists to avoid the Norcott Hill roundabout.
Shortly before 13:00, the fire service said the fire was under control and some crews were leaving the scene. It added that operations were continuing to ensure the fire was fully extinguished.
