There was a terrible chain reaction accident on a highway in Italy that caused two massive explosions. You can see the first fireball happened when a tanker truck plowed into another truck. That fire spread and caused a second, even bigger explosion. Here's a tip especially for the dude driving the blue truck on the right. DO NOT STOP NEXT TO A TANKER THAT IS ON FIRE. Usually that doesn't ahve to be explained. The worst part of all this is at least three people were killed and over sixty were injured.
