Firefighters tackle large blaze
A massive plume of smoke billowed into the sky after a fire broke out near gas containers.
Dark clouds were reportedly visible up to 20 miles from the yard where 12 fire engines tackled the blaze.
People living locally were evacuated from their homes in Gravesend, Kent, as flames ripped through caravans, tyres and other vehicle parts.
Eyewitnesses described seeing a "massive fog of black smoke" on Twitter where some reports suggested the fire could be seen on beaches in Southend, Essex.
Emergency services said the gas holders close to the yard, on Canal Road, were not affected by the blaze.
There were no reports of injuries.
Kent Fire and Rescue Service said: "Crews are using three main jets to tackle a large fire involving caravans at a yard on Canal Road in Gravesend.
"Local residents are being advised to keep their windows and doors shut due to the amount of smoke in the area."
