The French public transport strike is to be extended by 24 hours and could affect England rugby fans travelling to the World Cup final in Paris on Saturday.
Thursday's strike, billed as France's biggest in years, had been due to last only 24 hours.
However, members of at least one union have voted to extend the action for another day and there are calls for daily votes to extend the action even further.
Sky News Online reporter Angela Corpe in Paris says fans will have difficulty getting around the city.
"We don't expect the strike to affect Eurostar trains from England too badly but there'll be chaos when fans all arrive together," she said.
"There are no trains, buses or tubes running and it's hard to get a taxi. But you can hire bikes! There are thousands of the silver-grey cycles for hire for a few Euros."
Today, high-speed train operator Eurostar cancelled three London to Paris services, as well as one London to Brussels train and two from Paris to London.
For Friday, the company has already cancelled two Brussels-London trains, one London-Brussels service and one Paris-London train.
Corpe says all hotels are fully booked for the final.
"I went to the airport tourist information desk to inquire about the availability of hotel rooms on Saturday night .
"All I got was a laugh and a "non".
"When I checked in to my hotel even the receptionist remarked surprise when she told me my room rate - 230 Euros. That's £160!"
At a news conference, England player Martin Corry told fans: "To see everyone getting behind the national side is wonderful. We want to do ourselves proud and the country."
Paul Robinson said: "The final is going to be a tough game and could be a classic."
