An explosion rocked the US city of Nashville at 6:32am on Christmas morning, damaging dozens of buildings in the downtown area.
Police believe the blast was deliberate, and the FBI is now investigating.
Don Aaron, a spokesman for the Metro Nashville Police, said the department had received a report of a suspicious vehicle. It dispatched the hazardous devices unit to the location, and then the vehicle exploded.
“We do believe that the explosion was an intentional act,” he said.
A short time after the incident, the bomb squad and fire hazmat team were on the scene. Firefighters were instructed to pull back two blocks from the site of the explosion in case there were other bombs.
Three people were taken to hospital. Their injuries were not life-threatening.
In a statement posted on social media, Tennessee Governor Bill Lee said the explosion occurred around Second Avenue and Commerce Street.
He confirmed that federal, state and local law enforcement were all investigating, and believed it was a deliberate act.
“We will supply all of the resources needed to determine what happened and who was responsible,” Mr Lee said.
“Please join me in praying for those who were injured, and we thank all of our first responders who acted so quickly this morning.”
“Metro Police confirm the source of the explosion came from a vehicle,” said Nashville Mayor John Cooper.
“The cause of the explosion is under investigation with help from federal authorities. Police will share updates as they become available, and is restricting downtown traffic.
“Be safe, Nashville. Thank you to our emergency personnel for your quick response.”
More to come.
