Icy temperatures and snow are causing problems across Western Europe.
In Paris, flights were delayed and snow caused several road accidents, although the state forecaster said the quantities of snow were not unusual.
Flights were delayed by at least half an hour at Paris's Orly and Roissy-Charles de Gaulle airports. One of Orly's two runways was closed.
Air France cancelled a third of short and medium haul flights from Charles de Gaulle Airport during the morning but said long haul routes would not be troubled
France's road traffic agency urged motorists to cancel non-essential journeys, with roads difficult and in a small number of cases impassable around Paris and in the east near Strasbourg.
