Does anyone have any idea of what has happened? There is a Stagecoach bus in-shot and it looks empty - perhaps it was involved in the accident? The person claims that 'there's about 10 police and 10 ambulance and 2 fire engines'... Chances are that this statement is a tad exaggerated, but nonetheless, they also said that 'the traffic is unreal'.

I believe the photo was taken from St. Peters Metro, looking down onto North Bridge Street (next to Wearmouth Bridge).
