Dozens of homes in a small town in Canada were destroyed and thousands had to run from their homes when a train derailed and exploded.
This was the scene in southern Quebec on Saturday.
At least five people were killed.
The train was actually shut down for the night and the conductor had checked into a motel, but the brakes somehow came loose sending 73 cars full of crude oil barreling into the town of Lac-Megantic.
Explosions created toxic flames and sent plumes of smoke into the air.
The Canadian prime minister toured the area yesterday and said it looks like a "war zone."
The transportation safety board of Canada is investigating.
