Video Of North Dakota Train Crash Fireball
A huge explosion sparked by an oil train crash in North Dakota has been caught on camera, as hundreds of residents were urged to leave the area.
There were fears of smoke overwhelming the town of Casselton after a number of carriages derailed, starting a series of blazes and sending an enormous fireball high into the sky.
Several explosions were reported and people said the blasts rattled the windows of properties in the area, including the town's City Hall.
Cass County sheriff's office said it was advising people in the town - which has 2,400 residents - to evacuate because of concerns about smoke being blown over their homes.
A shelter was set up in Fargo, about 25 miles (40km) away.
Investigators say they are still trying to work out what caused several of the carriages from the mile-long train to leave the tracks on Monday afternoon.
They said it appears to be the result of the train colliding with a grain carriage.
There were no reports of injuries as firefighters brought the scene under control on Monday evening.
