This is a rare sight. Amateur video captures the moment when twin tornadoes touch down in the U.S. state of Nebraska.<br/> <br />But it's happened not once but twice.<br/> <br />Here a pair of twisters slam into the town of Pilger simultaneously.<br/> <br />And in different footage another couple strike in Wakefield, tearing up farmland.<br/> <br />The swarm of tornadoes were part of a super thunderstorm system, packing winds of up to 265 kilometres per hour (165 miles).<br/> <br />The small town of Pilger appeared to have sustained the worse damage.<br/> <br />At last one of the tornadoes directly hit, devastating the town.<br/> <br />More than a dozen people were injured in the powerful winds and at least one person was killed.<br/> <br />Here in Wakefield a farm is flattened and the debris from damaged buildings can be seen spiralling around the funnels.<br/> <br />A state of emergency has been declared in Nebraska and rescue crews are scrambling to dig for victims trapped under the rubble.
