A powerful tornado has been caught on camera moving through the US state of Minnesota and destroying a house on its way. The twister touched down in Wilkin County, near the North Dakota state border. The footage, captured by a storm chaser ( http://www.youtube.com/user/SevereStu… ) shows the tornado crossing a road, then hitting a farmhouse and scattering debris. It could not be immediately verified if there were people inside the house. No injuries have been reported.
