Hundreds of passengers have been evacuated from a broken-down train inside the Channel Tunnel, causing delays of up to four hours for other services.
The Eurotunnel shuttle train, which was heading to France, came to a halt around 7.30am, seven miles into the 30-mile long tunnel.
It stopped after a problem with the overhead power line.
Some 382 passengers and four dogs were taken off the train and then transferred to the French terminal where they waited for it to be brought out of the tunnel so they could get their cars back.
Services through the tunnel, using the one unblocked tunnel, were able to continue.
But Eurotunnel warned services were being delayed, with hold-ups possibly lasting for the rest of the day.
The company said in a statement: “Our passenger service is currently operating with some timetable disruption. This is due to an incident in the tunnel which is in the process of being resolved.
“There is a waiting time of approximately 60 minutes before check-in and three hours on the terminal.
“We sincerely apologise for the inconvenience this will cause to your journey.”
Eurostar said that if journeys were not essential passengers would be able to exchange tickets, free of charge, to another available service within the next four months.
