Not a joke, it looks like domestic terrorism:
Nashville authorities believe an explosion that occurred in downtown Nashville early Christmas morning was an “intentional act” and sparked by a vehicle.
Police responded to reports of a suspicious vehicle parked outside an AT&T building just before 6 a.m. Upon arrival, police said an officer “had reason” to alert the department’s hazardous devices unit, which was en route, when a “significant explosion” happened.
Three people were hospitalized with injuries, police said.
No clues in the article as to who or why, or even why today or why Nashville, but that’s the way terrorists work.
UPDATE 1: Andrew McCabe, former FBI deputy director, said on CNN: “An explosive device of this size is going to be treated presumptively as an act of terrorism.”
