The teenage gunman accused of shooting 10 people dead in a supermarket in Buffalo, New York, last month has been charged with domestic terrorism.
Prosecutors allege 18-year-old Payton Gendron, who earlier pleaded not guilty, was motivated by racial hatred.
The suspect, who describes himself as a white supremacist, is accused of shooting 13 people in total during the massacre – almost all of them black.
He will also face 10 separate first-degree murder charges.
The domestic terrorism charge filed on Wednesday accuses the suspect of killing “because of the perceived race and/or colour” of his victims.
In addition, the 25-count indictment includes multiple murder charges and attempted murder as hate crimes, as well as weapon possession charges, news agency AFP reports.
