Americans and Canadians faced disruption over Christmas Day as a severe winter storm caused power cuts and travel restrictions across North America.
A driving ban has been imposed in the Buffalo area of New York state, where even emergency service vehicles are stuck in the snow.
Canada also saw flights canceled and four people killed when a bus rolled over an icy road near Merritt.
At least 34 people are known to have died in the US from the winter storm and thousands lost power.
