10 killed in racially motivated US shooting

A heavily armed 18-year-old white man shot 10 people dead at a Buffalo, New York grocery store in a "racially motivated" attack that he live-streamed on camera.

The gunman, who was wearing body armor and a helmet, was arrested after the massacre, said Buffalo Police Commissioner Joseph Gramaglia.

He was identified as Payton Gendron of Conklin, New York.

Gramaglia put the toll at 10 dead and three wounded. Eleven of the victims were African Americans.

The gunman shot four people in the parking lot of the Tops supermarket, three of them fatally, then went inside and continued firing.

Among those killed inside the store was a retired police officer working as an armed security guard.

The guard "engaged the suspect, fired multiple shots," but the gunman shot him, Gramaglia said. He added that when police arrived, the shooter put the gun to his neck but was talked down and surrendered.

Stephen Belongia, special agent in charge of the FBI's Buffalo field office, said the shooting was being investigated as a hate crime. "We are investigating this incident as both a hate crime and a case of racially motivated violent extremism," Belongia said.

Erie County Sheriff John Garcia described the attack as "pure evil." Officials are reportedly investigating a detailed "manifesto" posted online before the shooting, in which the suspect outlines his plans and racial motivations for the attack.

Quoting from the manifesto, the New York Times reported the suspect had been "inspired" by white supremacist acts of violence, including the massacre of 51 Muslims in Christchurch, New Zealand in March 2019.

A semi-automatic weapon used in Saturday's shooting also had a racial epithet written on it as well as the number 14 - a reference to a white supremacist phrase.

District Attorney Flynn said in the press conference that the shooter used an "assault weapon" - a term that can apply to types of rifles and shotguns in New York - but did not specify which kind.

Flynn's office said in a tweet the suspect had been arraigned on a charge of first-degree murder, which carries a sentence of life without parole.

He is being held without bail.
