US winter storm: Severe weather continues to cause disruption
Americans and Canadians faced Christmas Day disruption as a severe winter storm caused power cuts and travel restrictions across North America.
A driving ban has been imposed in New York state’s Buffalo area, where even emergency service vehicles have been stranded in the snow. Canada also saw cancelled flights and train cancellations following a derailment.
Over 20 people are know to have died in the US due to the winter storm, and thousands have been left without power.
