Mr Williams says that now, 'no vehicle is safe' from Calais 'war zone'

They chopped down trees and set fire to them to block the carriageway

Migrants had chainsaws and threw Molotov cocktails into road, he said

A British motorist is warning tourists to avoid Calais after migrants wielding chainsaws smashed up his Mercedes and hurled petrol bombs in the road.

Rhys Williams, 53, was approaching the French port in the early hours when migrants from the sprawling jungle camp smashed his windows, causing up to £3,000 of damage.

They ran onto the road brandishing chainsaws and throwing Molotov cocktails at the police and passing traffic in scenes that he said 'resembled a war zone'.

The attack is the latest in a string of incidents where migrants have attacked cars in a bid to block roads so they can access lorries bound for the UK.

Mr Williams, an operations manager for the Road Haulage Association, was left covered in glass after his front and back door windows were shattered.

Mr Williams said: 'I was on the pitch black approach road to the port at about 1am in the morning when there was an almighty bang to the side of my car.

'Two or three migrants had thrown a massive boulder that smashed my windows and damaged the rear door, driver's door and the pillar in-between.

'Two police vans were trying to contain 50 to 60 migrants that had come onto the carriageway with chainsaws and Molotov cocktails, throwing them at the trucks, the traffic and the police.

'They were chopping down trees and setting fire to them to block the road, there was no way the police could cope.

'In the middle of all this was a small family car, the occupants were clearly distressed.

'It was something that I can only imagine would resemble a war zone.'

Mr Williams, from Bicester, Oxfordshire, says the incident on August 4 should be a warning to holidaymakers heading through the port.

He said: 'They used to target the trucks but now it has taken another slant, no vehicle is safe, they are doing anything they can to stop the traffic so they can climb into stationary trucks.

'I don't want to scare people but with the next two weeks being peak holiday season there will be a lot of people making their way to Calais, it's really not a place families should be travelling through.

'I was covered in glass in my car, I dread to think what could have happened if there was a child in the back.

'My car is still in the body shop, the cost of repair will be £2,000 to £3,000 plus the cost of a hire car.

'Unless the authorities do something soon someone will be killed, that's not scaremongering, it could be a lorry driver or a holidaymaker.'

Migrants from the Calais camp, which has a population of 9,000 and rising, have been trying to board vehicles to gain entry to the UK.

Rhys added: 'Migrants are trying to get into the UK are now using very sophisticated techniques to get into vehicles.

'The drivers are liable to pay £2,000 per migrant found in their trucks - it's a huge worry for them.

'The RHA is calling for the French military to intervene, the police have been stretched to their limits with the terror attacks.
