Buffalo shooting: At least 10 killed in attack at supermarket in New York state

At least 10 people have been killed in a mass shooting at a supermarket in the US city of Buffalo, New York state, AP has reported.

The gunman is reported to have been taken into custody after the attack on Saturday afternoon.

The exact number of people hurt at the Tops Friendly Market in Jefferson Avenue is yet to be confirmed.

AP said they had been told at least 10 had died by law enforcement officials.

The Buffalo News said the attack had been carried out by a gunman dressed in body armour and armed with a high-powered rifle.

One of the officials who spoke to AP said the gunman entered the supermarket with a rifle and opened fire.

The official added that investigators believe the man may have been live-streaming the shooting and are looking into whether he had posted a manifesto online.

The official said investigations were in their early stages and although a clear motive was yet to emerge, they are looking into whether the shooting was racially motivated.

SWAT teams rushed to the scene, which is in a predominately black neighbourhood, about 3 miles (5km) north of downtown Buffalo.

Police have not officially responded to a request to provide further details after a tweet was put out by the Buffalo Police Department (BPD) saying that multiple people had been shot.

Will G., a dairy frozen worker at the Tops supermarket, told the Buffalo News he walked into the refrigerated section 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 paper. "It sounded like things were falling over."

The worker hid in the section and more people joined him, he said, adding: "I hid. I just hid. I wasn't going to leave that room."

A law enforcement official on the scene told the paper: "It's like walking onto a horror movie, but everything is real. It is Armageddon-like. It is 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 location.

A large police presence has shut down the area north of Jefferson Avenue at Northampton Street, Buffalo News reported.

Governor Kathy Hochul tweeted that she was "closely monitoring the shooting at a grocery store in Buffalo," her hometown.

She said state officials have said they will help local authorities.
