Several Eurostar trains to Paris have been cancelled and others have been diverted following the arson attacks today.

The rail operator, which runs international services from London St Pancras, confirmed its trains would be delayed because of the ongoing issues over the Channel.

Eurostar said that ‘all high-speed trains going to and coming from Paris are being diverted via the classic line today’.

It added: ‘This extends the journey time by around an hour-and-a-half. Several trains have been cancelled.

‘Eurostar’s teams are fully mobilised in stations, in the call centres, and onboard to ensure that all passengers are informed and can reach their destination.’

The company said customers were being informed via email, text and on the Eurostar website.

Any affected passengers can cancel or refund their tickets or modify their journey free of charge.
