At around 6:27 on Christmas morning, what appears to be an intentionally-set bomb detonated on Second Avenue in downtown Nashville just outside an AT&T infrastructure building.

The Metro Nashville Police Department reports the bomb was inside a vehicle, believed to be a recreational vehicle (RV.) No one was killed and three people were reported injured.

FBI representatives said they will bring in the ATF and technical experts to assess the “massive crime scene.”

The area is sealed as is air space above downtown and WeGo, Nashville’s Metro Transit Authority, has suspended all service as the WeGo Central station is blocks away.

There is little information on who perpetrated the crime or what the motive was at this point. The Federal Bureau of Investigation (FBI) has assumed responsibility for the investigation.

This is a developing story and we will continue to cover it.
