Huge snowstorm strikes north-eastern US
The north-eastern US states of New York, New Jersey, Pennsylvania and Virginia have declared states of emergency as a huge winter storm sweeps in, bringing heavy snow.
The US National Weather Service issued blizzard warnings from eastern Pennsylvania to south-west Maine.
Schools are closed and thousands of flights have been cancelled.
The conditions caused German Chancellor Angela Merkel to postpone a trip to Washington to meet President Trump.
It has now been rescheduled for Friday.
With winds of up to 60mph (100km/h), the storm is expected to cause severe disruption for commuters across many parts of the north-east.
In all, about 50 million people across the country have been warned about the severe weather.
There has also been heavy snow in other parts of the country. In the state of Wisconsin, four people aged over 60 died in separate incidents while shovelling snow, according US media.
Less snow than anticipated is now expected to fall in New York City, with the forecast downgraded to between 4 and 8 inches (10-20cm) by the US National Weather Service.
However, up to two feet of snow was still expected other parts of New York state, the service said.
