Severe winter weather continues to disrupt travel in Germany, forcing the cancellation of more than 200 flights and contributing to road accidents. At Frankfurt airport, 226 flights were cancelled and hundreds of passengers stranded as snow ploughs struggled to clear runways. Residents have been advised to stock up on enough essential supplies to last up to four days.<br/><br/>Many other countries across Europe have also been hit by the bitter conditions. Nearly 140 people have frozen to death in the past few weeks in Poland and in Switzerland heavy snow has cut the flow of lorries through Alpine tunnels.<br/><br/>The Eurostar service between Britain, France and Belgium ran a limited service yesterday with a reduced service planned for today and tomorrow. Passengers have been urged to cancel or postpone their journeys if they do not have to travel.<br/><br/>Germany's Civil Protection Office (BBK) said heavy snowfalls over the weekend could trigger local power cuts and severely disrupt public transport.
