“More than 5,000 residents of the US state of Tennessee have been evacuated after a freight train carrying toxic chemicals derailed and caught fire.
The train was carrying a flammable, toxic substance called acrylonitrile when it came off the rails near Maryville, just outside Knoxville.
Firefighters evacuated people within a two-mile radius of the fire to prevent them breathing in the poisonous fumes.”
