Heavy snowfalls and freezing rain across Germany on Wednesday led to the cancellation of hundreds of flights and trains, crashes on icy roads, and school closures.

At Frankfurt airport, Germany's biggest, more than 500 flights were canceled, while in Munich over 250 arrivals and departures were canceled. In western Germany, Saarbruecken airport closed for the day, as Duesseldorf and Cologne/Bonn airports were also affected by delays and cancelations.

National train operator Deutsche Bahn cancelled several long-distance connections and announced that the maximum speed of its fast ICE train would be limited to 200 km per hour (124 miles per hour) due to the extreme weather.

The freezing rain across western and southern Germany also led to countless crashes on icy roads in the early morning hours of Wednesday. As a precaution, many schools and kindergartens in the country closed for the day, and some companies offered their employees the option of working from home.

According to another report, freezing rain in central and southern Germany grounded hundreds of flights and restricted train traffic on Wednesday as the weather service warned of slippery roads and heavy snowfall.
