A 'lake-effect' snow storm produces a wall of snow over Lake Erie, Buffalo
At least five people have died in New York after a huge storm dumped large amounts of snow on the US north-east.
Buffalo bore the brunt with 5ft (1.5m) of snow, but temperatures across all 50 US states plummeted to freezing.Forecasters predict an additional 2ft could fall on the region as residents struggle to dig out.
One New York man was found dead in his car buried in a snowdrift, while at least three others died from heart attacks while shovelling snow.
"We have tried to get out of our house, and we are lucky to be able to shovel so we can open the door," said Linda Oakley told the Associated Press news agency.
"We're just thinking that in case of an emergency we can at least get out the door," she added. "We can't go any further."
Residents were reported trapped in their homes and cars, and strong winds and icy roads caused motorway accidents and forced school closures in parts of the US.
