Heavy snowfall and blizzards have caused widespread travel disruption across Europe, leaving at least six people dead. Five fatalities were reported in different regions of France due to road accidents, while one woman died in Sarajevo, Bosnia, after a tree collapsed under heavy wet snow. In France’s Landes area, three people were killed in two separate accidents, and two others died in the Paris region in weather-related crashes.

The severe weather has also led to the cancellation of hundreds of flights across the continent. Thousands of passengers were stranded at airports in Paris and Amsterdam. More than 400 flights were canceled at Amsterdam’s Schiphol Airport on Wednesday, while Paris’s Charles de Gaulle Airport temporarily suspended about 40 percent of its flights, and Orly Airport canceled roughly one-quarter of scheduled departures.

French Transport Minister Philippe Tabarot warned of further snowfall and urged residents to avoid unnecessary travel and work from home if possible. France’s national meteorological agency issued orange alerts in 38 districts, with conditions expected to persist through Wednesday.
