Police believe an explosion in downtown Nashville that hospitalized three people and damaged 20 buildings was an "intentional act." 

Police responded to reports of a suspicious vehicle parked outside the AT&T building just before 6 am on Christmas morning. After an officer alerted the department's hazardous devices unit, which was en-route, a "significant explosion" happened. Nashville Mayor John Cooper revealed that three people were sent to the hospital with injuries, while 20 buildings were damaged.
