The US is enduring another bout of severe winter weather, as a succession of powerful weather systems brings heavy snow, freezing rain and extreme cold temperatures to much of the country.
Twenty-six states, from Texas to Massachusetts, were under storm warnings issued by the National Weather Service over the weekend, with many alerts remaining in place this week.
Heavy snow began falling in parts of north Texas and Oklahoma on Friday evening before pushing eastwards. By Sunday, swathes of the central and eastern US were experiencing either heavy snow or freezing rain, causing widespread travel disruption.
In parts of Mississippi, Tennessee and Kentucky, about 2.5cm (1in) of ice coated cars, roads, trees and downed power lines. Snow and freezing rain continued to track north-east into cities including New York and Philadelphia, where some areas recorded 30-50cm of snowfall.
