Video: Oil worker captures amazing footage of tornado ripping through North Dakota
A US oil worker has captured incredible footage of a tornado bearing down on a workers' camp in North Dakota on Monday which injured nine people.
The footage starts with two men laughing and joking as they look out from a mobile home near Watford City at the monstrous twister approaching them.
They continue to film the tornado from almost directly underneath the funnel as debris flies past the window and people run for cover around them.
According to reports, the tornado damaged or destroyed 15 trailers and left nine people injured, including a 15-year-old girl.
According to the Red Cross, the safest place to be during a tornado is in an underground shelter or basement.
Cars and mobile homes are among the worst places to be caught during a tornado as they offer almost no protection.
