A bin lorry has smashed into a crowd of Christmas shoppers in Glasgow city centre, killing six people.
The crowd were waiting to cross the road outside Queen Street station by the Millennium Hotel in the centre of the city and some people are thought to have been thrown up to 15 metres from the site of impact.
As many as six ambulances are at the scene, along with the police and fire service and pictures on social media show people being treated along the length of the street.
Superintendent Stewart Carle of Police Scotland said that it appeared "at least" seven people had been seriously injured but warned that "that number may rise".
Sky correspondent James Matthews who is at the scene asked the witness to tell him about the people on the pavement who had been hit.
The distressed woman said: "I can’t, honestly I just can't do that."
She went on to say: "When something is coming up behind them like that, how can they run out of the way? It's such a horrific thing. There was noise and bangs and screams.
"There was a baby in a buggy. There were actually two little kids. It was just horrific."
My whole heart dropped 'cause my little Sister is always at George Sq due to the ice skating. Had to call and make sure. Such a tragedy. My heart goes out to all of those injured and their families.
Hope everyone in town is staying safe. Absolutely tragic, from The Clutha last year to this. RIP to those who sadly lost their life, my thoughts to their families too.
