What began as a rare chance for winter fun in Texas has ended in heartbreak. A 16-year-old girl has died and another teenager is in a critical condition after a sledding accident in the city of Frisco, becoming one of at least 14 people killed as a huge winter storm batters large parts of the United States.
The fatal crash is the most poignant illustration yet of how quickly this 'historic' cold spell has turned deadly. From New York to Tennessee, Louisiana, Massachusetts, Kansas and Texas, authorities are linking multiple deaths to the storm, while hundreds of thousands have been left without power and much of the transport network has ground to a halt.
