of the road forcing many lorries to slow down

A dramatic video has emerged of flames blazing across a Calais road in the latest attempt by migrants to prevent lorries from passing.

The frightening dashcam footage shows lorries being forced to drive straight through the fire so the migrant men don't have time to board their trucks.

Many of the lorries - all of whom have their hazard lights flashing - are forced to slow down as they approach the blaze, and some cars have stopped completely at the side of the road.

The flames lick the width of the tarmac, clouds of smoke billowing up into the night sky

The flames lick the width of the tarmac, clouds of smoke billowing up into the night sky as various men can be seen running across the road and leaping over barriers.

Just like the truck in front, the lorry filming shows no sign of stopping and ploughs straight through the flames - which mercifully appear to cause no harm - and the remainder of his journey seems unhindered.

The alarming scene is one of many similar attempts by migrants this summer to block passing vehicles.

In August rioting Calais migrants were accused of threatening a lorry driver with a chainsaw and pouring petrol across a road and setting it alight during a night of violence.

Further barricade attempts have seen hay bales, tyres and wood set alight obstruct roads.
