Two storm chasers in the US have driven into the centre of a tornado where they withstood wind speeds of up to 300 km/h (186mph).
Brandon Ivey and Sean Casey were able to film the footage on Monday afternoon in Kansas using cameras inside a specially adapted vehicle, which is able to withstand heavy winds.
