Nashville authorities announced Sunday that they identified the man suspected of carrying out the bombing that destroyed part of the historic center in Tennessee on Christmas Day, explaining that he was killed in the explosion.

"We concluded that the person named Anthony Warner was the bomber. He was present when the bomb exploded and died in the blast," federal prosecutor Don Cochran said at a press conference.

Doug Korniski, the main official in charge of the investigation at the FBI, said, "There are no indications of the involvement of other persons," noting at the same time that investigations are being conducted into many hypotheses.

Representatives of the authorities who attended the press conference explained that Anthony Warner was not known to them.

Media reported that the authorities revealed the identity of the bomber, 63-year-old Anthony Warner, Saturday. However, the police only said at the time that there was a person wanted for investigation. 

A caravan blast early Friday morning destroyed a historic quarter in the country music capital of the United States.

Before the explosion, the port broadcasted a terrifying recording via a loudspeaker, calling on people in the vicinity to evacuate. For this reason, and despite the severity of the explosion, only three people were injured.

David Roche, head of the Tennessee Bureau of Investigation, said that DNA analysis of human remains found at the site of the explosion had allowed the identification of the perpetrator.

The police confirmed that it was a "premeditated act," but investigators are still trying to determine the motive.

Tennessee Senator Marsha Blackburn said on Twitter that she had asked President Donald Trump to declare Nashville a disaster area, a measure that would allow the release of federal aid to repair the damage.

According to a sequence of facts presented by the authorities, the police received a report of shooting in the area at 0530 hours, and the police identified the camper van 30 minutes later.

The caravan was parked in front of the AT&T communications company, and its explosion damaged facilities and disrupted communications in Tennessee and some areas in Alabama and Kentucky. Even the local airport had to suspend flights for a while.

AT&T said Saturday that two mobile phone antennas had been installed in downtown Nashville and a number of others were in the area to resume communications.
