Icy US weather continues to cause disruption

Icy weather conditions have been causing severe disruption to parts of the United States.

Snow and ice storms have been followed by plummeting temperatures across the south, mid-Atlantic region and north-east.

It left stunning scenes in places like Niagara Falls - but caused problems for people on the roads and in their homes.

Forecasters are warning the weather could be even colder later in the week.
