Hauliers have called for the French military to be deployed in Calais after hundreds of migrants blocked the port and boarded a passenger ship.

The Road Haulage Association (RHA) claims the incident shows that the migrant problem in and around the town is not being tackled, leaving British truck drivers to face attacks and intimidation on a daily basis.

Security forces were drafted in on Saturday after 350 migrants descended on the port and some boarded P&O's Spirit Of Britain ship.

Pictures posted on social media showed hundreds of people running towards the port and water cannons reportedly being fired to get migrants to disembark.

RHA chief executive Richard Burnett said: "This shocking breach of security clearly shows that the migrant mayhem in and around Calais is not being tackled.

"This latest episode has made the headlines, but the many incidents of attacks and intimidation faced by our British drivers on a daily basis are going unreported as, depressingly, they are now being regarded as routine.

"It is now time for the authorities to acknowledge and meet our demand for the French military be deployed to secure the port and its approaches."

Mr Burnett said immediate action was necessary, warning it is "only a matter of time before our worst fears become a reality and a UK-bound truck driver is killed".

Trouble flared after hundreds of people marched towards the port from the Jungle site where some 4,000 migrants and refugees are camped.

Following the breach, French Interior Minister Bernard Cazeneuve said the country's government had a total determination to maintain law and order.

He revealed 35 people, including 26 migrants and nine activists, were arrested, with fifteen being taken into custody.

In a statement, he added that mobile forces, including CRS and squadrons of gendarmes, supported by territorial units and border police, had been mobilised for several months.

And he said significant work had been done around the Channel Tunnel and Calais port with the help of the British authorities to prevent disorder.

Humanitarian solutions had also been implemented, including accelerated asylum procedures, which had helped reduce migrant numbers at Calais to 6,000 from 4,000 in recent months, Mr Cazeneuve went on.

The trouble broke out on the same day Labour leader Jeremy Corbyn visited the Jungle and the Grande-Synthe migrant and refugee camp near Dunkirk.

In ankle-deep mud, he toured Grande-Synthe, where around 2,500 mainly Kurds are sleeping rough in the cold in flimsy tents, and said the conditions were a "disgrace".

Volunteer Azzam Mohammed, of Glasgow Ahlulbayt Association, was at the site to hand out supplies to refugees shortly after the incident.

In an interview with Good Morning Scotland, he said security made it difficult for his team to get into the site.

"There was lots of security from the police," he said. "There were protests everywhere in Calais.

"It was actually very difficult to enter the camp. We kept going around and around because the police refused to let us enter the camp at first."

He added that the situation in the camps seem to worsen each time they visit with supplies and issued a call for Scots to donate warm clothing and supplies to help those in need.

A statement from the Port of Dover said the Port of Calais reopened more than two hours after experiencing "migrant activity" which disrupted cross-Channel services.
