Justin Bieber holds moment of silence for supermarket shooting victims during concert

Justin Bieber led a moment of silence for the victims of a supermarket shooting in Buffalo, New York during his concert in the city on Saturday.

An 18-year-old gunman opened fire in the supermarket, killing 10 people and wounding three others on Saturday, and hours after the tragedy, Justin took to the stage at the city's Keybank Center and made sure to honour the victims of the incident.

"It's such an honour to be back here. As you know, there's been tragedy in the city, but what we're gonna do tonight, is we're gonna honour those people, and I would love if we could just take a moment of silence. That would mean a lot to me," he said to the audience before bowing his head in silence on stage.

Silence fell around the auditorium and the crowd later cheered Justin when he resumed the show.

Sharing a video of the moment on Instagram on Sunday, the Peaches singer wrote in the caption: "To the people who couldn't stay silent to honor the lives that were so tragically lost, I urge you to ask yourself why."

The 28-year-old also posted a video showing the speech he gave to his crew backstage before the show.

"You guys probably heard what happened," he said during a pre-show huddle. "Pretty horrible stuff. But I'm looking forward to tonight, looking forward to getting on that stage and doing what we do best and having a good time and bringing joy to the city. It's much needed. So let's just do that."
