The Port of Dover is facing delays of up to one hour today as Eurotunnel services are disrupted by "migrant invasion".

DFDS Seaways says its Dover to Calais services are running with a maximum delay of 60 minutes. Customers are advised to arrive at the port on time.

P&O Ferries is also experiencing delays of 10-40 minutes on its Calais services.

Other services to Dunkirk are running on schedule.

The delays come as Eurotunnel travel remain severely disrupted after being suspended earlier following a "massive invasion" of more than 100 migrants.

A "large and co-ordinated" group broke through fences and stormed the Channel Tunnel in Calais at around 12.30am, Eurotunnel said.

Customers who planned to travel via Eurotunnel have gone to the port instead, meaning it is currently very busy.
