The inflatable roof of a football stadium in Minneapolis dramatically collapsed after severe cold weather blanketed large parts of the US in heavy snow.
Video footage taken inside the stadium shows the roof buckling under the weight of the snow before tearing in several places.
The damage forced the delay and relocation of an American Football game between the Minnesota Vikings and the New York Giants.
The storm dumped 17 inches of snow on Minneapolis, the heaviest fall in 19 years. Concerns about high winds endangering the crew clearing snow from the roof delayed work to remove it. No one was injured in the collapse.
The stadium roof has deflated three times before, each time because of heavy snow.
