Three enthusiastic young "storm chasers" have been killed after racing to keep up with a devastating tornado as it tore across Kansas.
Nicholas Nair, 20, Gavin Short, 19, and Drake Brooks, 22 have been identified as the three people killed in a car crash in neighbouring Oklahoma on Friday night.
The meteorology students at the University of Oklahoma had earlier in the day been posting videos on Twitter showing the twister passing over the highway as they drove, and even sent a selfie from their car to pals just hours before the crash.
