At least 10 people have been killed in a mass shooting at a supermarket in the US city of Buffalo in the state of New York, the AP reports.
The perpetrator is reported to have been remanded in custody after the attack Saturday afternoon.
The exact number of people injured at Tops Friendly Market on Jefferson Avenue has not yet been confirmed.
The AP said they had been told at least 10 had died by law enforcement officials.
Buffalo News said the attack had been carried out by an armed man dressed in armor and armed with a powerful rifle.
One of the officials who spoke to the AP said the gunman went into the supermarket with a rifle and opened fire.
The official added that investigators believe the man may have live-streamed the shooting and are investigating whether he had posted a manifesto online.
The official said the investigation was in its early stages and although a clear motive had not yet emerged, they are investigating whether the shooting was racistly motivated.
SWAT teams rushed to the site, which is in a predominantly black neighborhood, about 3 miles (5 km) north of downtown Buffalo.
Police have not officially responded to a request for further details after a tweet was issued by the Buffalo Police Department (BPD) saying more people had been shot.
Will G., a dairy frost worker at the Tops supermarket, told Buffalo News that he went into the refrigeration department to put milk on the shelves about three minutes before the shooting.
“I just heard shots. Shots and shots and shots,” he told the local newspaper. “It sounded like things were falling apart.”
The worker hid in the section and several people joined him, he said, adding, “I was hiding. I was just hiding. I was not going to leave that room.”
A law enforcement official at the scene told the newspaper: “It’s like going into a horror movie, but everything is real. It’s Armageddon-like. It’s so overwhelming.”
WBEN radio news reported that Buffalo Mayor Byron Brown, BPD Commissioner Joe Gramaglia and Erie County District Attorney John Flynn have arrived at the scene.
A large police presence has closed the area north of Jefferson Avenue at Northampton Street, Buffalo News reported.
Governor Kathy Hochul tweeted that she “closely monitored the shooting at a grocery store in Buffalo,” her hometown.
She said government officials have said they will help local authorities.
