Cross-Channel travellers faced another round of disruption in their journeys on the Channel Tunnel after migrants invaded the Eurotunnel terminal in France.
Freight traffic was being disrupted but there were also delays to passenger services following the intrusion near Calais in the early hours of the morning, Channel tunnel operator Eurotunnel said.
The incident comes days after around 150 migrants caused delays and cancellations when they tried to storm the Channel Tunnel terminal in France.
There have been increased calls for a resolution to the migrant crisis in Calais. The Eurotunnel spokesman added: “We are working very hard to restore full services as soon as possible.”
The migrant crisis in Calais has escalated in recent months, with around 3,000 people displaced from countries including Eritrea, Syria and Afghanistan setting up camp near the port.
Last week more than 3,000 truckers had to queue for several days in high temperatures on the M20 following a wildcat strike by ferry workers in France.
Industrial action by ferry workers this summer has come on top of the problems faced by truckers with migrants desperately trying to clamber on board their HGVs to the UK.
French authorities have faced claims they are not doing enough to safeguard lorry drivers from intimidation, violence and attempts by migrants to climb on.
