Ten people have been killed in a shooting at a supermarket in New York state.
An 18-year-old man has been arrested at the scene in the city of Buffalo.
He has not been named by police.
Police said the suspect entered the busy supermarket on Saturday before opening fire while using a camera to live-stream the attack online.
The FBI is investigating the shooting – which left three other people injured – as a racially-motivated hate crime.
