A derailed train has caused a huge explosion and fire in Colombus, Ohio in the United States.
Eleven carriages came off the track – several of them were carrying a flammable substance called styrene as part of a cargo of agricultural chemicals.
It is also dangerous if inhaled, leading authorities to evacuate an area of more than 1.5 kilometres around the blaze.
Heavy plumes of smoke could be seen rising into the sky from the overturned wagons.
Two people were injured in the crash and taken to hospital.
An investigation is underway into what caused the train to derail.
