Nashville Bombing

I have not even the faintest idea what might be going on here:
An explosion rocked downtown Nashville on Christmas morning, sending smoke rising high above the city, blowing out store windows and forcing evacuations. Authorities said they believed the explosion was an “intentional” act.
Officials said at a news conference that three people were injured and taken to hospitals. So far, there are no fatalities, they said.
An explosion “linked to a vehicle” occurred at 6:30 a.m. outside 166 2nd Ave N in downtown Nashville, the Metro Nashville Police Department said on Twitter. Police said that they did not know whether a person was inside the vehicle, an R.V., when it exploded.
An intentional explosion that goes off at 6:30am on Christmas Day? Terrorism is about messaging, and I’m struggling to understand the message. Perhaps an error in bomb design?
