Ten people have been killed by a gunman in the United States, in an attack which police think was racially motivated.
Detectives have arrested an 18-year-old white man who they say was wearing body armour and military style clothes when he went into a supermarket in Buffalo in New York State.
Black workers and customers are mostly the victims.
Buffalo Police Commissioner Joseph Gramaglia says the gunman was also wearing a camera:
"He was very heavily armed , he had tactical gear, he had a tactical helmet on, he had a camera that he was live streaming what he was doing."
