Snow disrupts travel across Europe

Thousands of flights and train rides have been cancelled across Europe because of snow and ice, leaving many travellers stranded.



Few flights are said to be leaving London Heathrow, Europe's busiest airport, and one third of flights were cancelled in major hubs like Paris and Frankfurt.



Roads in a number of countries have also been described as treacherous.



The UK, France and Germany were among the worst-hit areas, with forecasters warning of freezing weather all week.



There were also severe delays on the Eurostar rail service between the UK and France and Belgium, and Thalys trains between France and Belgium were also affected.
