The explosion in Nashville, US, that injured at least three people and damaged dozens of buildings is believed to be an intentional act.

Iran Press/America: Officials believe that a Christmas morning explosion in downtown Nashville that injured at least three people and damaged dozens of buildings was an intentional act, CNN reported.

In a brief news conference Friday morning, Metro Nashville Police spokesman Don Aaron said the department's hazardous devices unit was headed downtown in response to a call about a suspicious vehicle when there was a "significant" explosion linked to that vehicle around 6:30 a.m. CT.

"We do believe that the explosion was an intentional act," Aaron said.

Three people have been transported to hospitals from the scene, but none are in critical condition, according to Nashville Fire spokesman Joseph Pleasant.

The incident is under investigation by multiple agencies, both local and federal, including the FBI and the ATF, Aaron said. Police and Tennessee Highway Patrol are conducting a shutdown of the area for the investigation. Access from the interstate through the immediate area will be restricted, he said.

Eyewitness Buck McCoy told CNN the explosion took place right in front of his home, causing his windows to be blown in.

"Everything on the street was fire," he said. "There were three cars that were fully engulfed."
