Explosions as US oil train derails
Wagons from a mile-long train carrying crude oil have burst into flames as they derailed after a collision in the US state of North Dakota.
A plume of thick black smoke could be seen many miles away and explosions were heard.
No injuries were reported, but officials ordered the evacuation of about 300 people from the nearby town of Casselton as a precaution.
Amateur footage caught some of the explosions.
