A group of oil workers have escaped a tornado, moments before it struck their camp in North Dakota, US.

At least 15 trailers were damaged or destroyed south of Watford City on Monday, with a 15-year-old girl suffering critical injuries.

Rescue crews are continuing to search through debris at the camp.

Dan Yorgason captured this footage as he fled.
