Eurostar services through the Channel Tunnel between London and the continent were ancelled on Tuesday due to a technical problem.
Eurostar warned passengers earlier today that its train services are severely disrupted due to several technical problems, and advised customers to postpone their travel.
According to the BBC, passengers arriving at London St Pancras are being told that "all services have been cancelled for today", with staff advising passengers to rebook for another day.
AFP are reporting that all cross-Channel services between London, Paris, Amsterdam and Brussels have been suspended.
Eurostar services between Paris and Brussels are also severely disrupted, though some trains appear to be running.
Le Shuttle, which provides train services for people and their vehicles through the Channel Tunnel, says passengers should expect three hour delays if travelling from Calais to Folkestone. Those travelling in the opposite direction should expect longer delays.
Train traffic will "gradually resume" this afternoon, according to the company which operates the Channel Tunnel.
Eurostar says some of its services will also resume, but it still strongly advises passengers to postpone their journeys to a different date.
An update from Eurostar said: "As the Channel Tunnel has partially reopened we will start to resume services.
"The overhead power supply issue remains, and we strongly advise all our passengers to postpone their journey to a different date.
"Please don't come to the station if your train is confirmed as cancelled. We regret that trains that can run will be subject to severe delays and possible last-minute cancellations.
"Please check for live updates on the status of your train on the Train status and timetables page."
This is a developing news story and we will bring you updates as they come in.
