It was “truly miraculous” that no one was killed in a 100-car pile-up on a bridge in the UK in heavy fog, police have said.

A 100-vehicle pile-up on a bridge in heavy fog has left at least six people seriously injured and 200 suffering minor wounds in what witnesses described as “carnage”.

More than 100 vehicles have been involved in an accident in misty conditions on a bridge in the UK and it is believed that there are serious injuries.
