A van driver was killed when he crashed into a tail-back on a motorway near Calais, northern France, where UK-bound migrants had blocked the road with tree trunks, sparking calls for higher security measures.

The Polish-registered van burst into flames when it crashed into trucks.

A spokesman for the Prefecture du Pas-de-Calais said the fatal crash took place at around 3.45am on Tuesday, between junction 49 and 50, near the town of Guemps.

He said: "This van hit one of the three trucks stopped by the block and set alight. The identity of the driver is not known at this stage, considering the state of the body."

"Nine Eritrean migrants found in one of the heavy goods trucks held up by the roadblock were arrested. They were taken into custody."
