Just found out about this.

Nashville police said: “This appears to have been an intentional act. Law enforcement is closing downtown streets as investigation continues.”

Cops were reportedly en route to the suspicious vehicle when it exploded.

Roughly 30 people were evacuated from upper lofts on Second and Broadway near Commerce Street in Tennessee.

The bomb squad is now requesting the fire department to put out small fires so that they can investigate what has happened.

The Tennessee Bureau of Investigation is sending agents and an Accelerant Detection K9 have also been sent to help investigate.

Special operations confirmed that they have received information that there could be additional devices in vehicles.

People have been advised to steer clear of vehicles in the downtown area.

The explosion led one building to collapse, and vehicles on the road have reportedly caught on fire.

The pictures at The SUN show considerable damage.  Will AP President-Select Kamala Biden to call for common-sense car RV control? No theories yet that I know of, except that we can expect many more such incidents and worse moving forward.

UPDATE: Reports of shots fired first, and a 15-minute warning about the bomb.
