(CNN) -- A part of Charles de Gaulle Airport in Paris was evacuated Friday due to the accumulation of snow on the roof and hundreds of flights were canceled because of a shortage of de-icing fluid, authorities said, as blustery winter weather snarled travel across Europe.
Nearly 2,000 passengers were moved from Terminal 2E to other parts of the airport, French authorities said, calling the measure "preventative".
Part of the roof of that terminal collapsed in 2004, shortly after the state-of-the-art building was inaugurated. Four people were killed, media reports at the time said.
About a foot of snow had fallen on the roof Friday by the time authorities decided to close the terminal, French media reports said.
Authorities were working to clear it and reopen the terminal. French authorities earlier Friday asked airlines to cancel half their morning flights to and from the airport because de-icing fluid was running low, they said.
That led to the cancellation of 400 flights Friday morning -- 200 arrivals and 200 departures.
Then, early in the afternoon, authorities asked airlines to scrap a third of their flights for the rest of the day.
Charles de Gaulle is the second busiest airport in Europe, after Heathrow in London. CNN
