This just happened in Bologna, Italy. A fuel truck failed to halt on a jammed lane and rear ended a stopped truck. The accident caused a fire, which then ignited the transported fuel, sparking an explosion.
The video contains a CCTV footage of the crash and the inferno that followed. Appended is a ground level footage of some passer-by who captured the explosion from the other side of the overpass.
