A police officer has died from injuries sustained while responding to a shooting outside the headquarters of the US Centers for Disease Control and Prevention (CDC), which is near Emory University.

The Atlanta police department said the incident, which took place on Friday, involved a "single shooter" who is now dead.

Police identified the officer killed as 33-year-old David Rose, who had two children with a third on the way, the BBC's US partner CBS News reported. He had been shot and taken to hospital, where he died of his injuries.

There have been no reports of any civilian injuries resulting from the shooting, Atlanta city mayor said.

US media, citing an unnamed law enforcement official, reported a theory that the alleged gunman believed he was sick as a result of a coronavirus vaccine.

Media reports also suggested the man's father had called law enforcement on the day of the shooting believing his son was suicidal.

CDC Director Susan Monarez said the centre was "heartbroken" by the attack.
