Two trains carrying oil collide and explode in Poland

Two cargo trains have collided in northeastern Poland, causing a fiery explosion. No injuries are confirmed yet. As 40 teams of firefighters worked to put out the blaze, a primary school was closed nearby as a precaution.

AP reports one train had been at a standstill, and was hit from behind. But Reuters video tells a different story. One train derailed and hit a train on a track next to it. Russian Today also states: Officials in the town of Bialystok said one train carrying tanks of oil was stopped on the tracks as it was hit from behind by another cargo train. The train, carrying tanks of oil, exploded immediately, and it is thought that seventeen of the 33 tanks had eventually burned.
