Six people have been taken to hospital and up to 10 vehicles have been damaged

Emergency teams were called to the crash scene on the A20 at Capel-le-Ferne just before 1320 BST.

Two cars and two lorries, believed to be foreign-registered, were involved in the main crash, police said.

Initial reports said 30 vehicles were involved, but Kent Fire Service said many people stopped at the scene and conditions were extremely foggy.

A spokeswoman said: "Lots of vehicles had stopped and there was quite a lot of fog - it might not have been initially clear as to who was involved in the collision."
