A train carrying petroleum products derailed in the middle of a small town in the Canadian province of Quebec earlier today.
The blast destroyed many buildings and sent flames hundreds of feet into the air.
Police in Lac-Megantic, a lakeside town of about 6,000 people, said they have been unable to determine if there were any casualties.
Fire officials said around 30 buildings in the town centre were destroyed, some by the initial blast and others by the subsequent fire.
