Authorities say an entire town in North Dakota is being urged to evacuate after several cars of a train carrying crude oil derailed and blew up 30 minutes west of Fargo.
It all started around 2p.m. on Monday when a passing train hit the oil car causing the explosion.
Thick, black smoke could be seen from around 15 miles outside of town. A shift in the winds could push portentially toxic fumes from the blaze. Crews are letteing the blaze burn itself out; investigators hope to get near the scene later Tuesday.
Authorities are urging the town's roughly 2,400 residents and people living five miles to the south and east to evacuate. However, it is voluntary.
Investigators are still trying to determine exactly what happened. A team from the National Transportation Safety Board is on the way to help figure out what caused the accident.
