The United States has been struck by a major winter storm in recent days, intensified by a polar cold snap.
The disaster has brought heavy snowfall, ice storms, and extreme temperature drops across the northern parts of the country.
At least 38 deaths have been reported in 14 States, while more than 800 000 homes have been left without power. These severe weather conditions have also forced the cancellation of thousands of flights.
Another winter storm is expected to hit the United States in the coming days.
