Several people have been injured after a bus crashed into a city centre building.
The single-decker bus was also involved in a collision with a car in Peterborough shortly before midday.
Police, fire crews, ambulance and an air ambulance attended the scene and the road between Church Walk and Broadway was cordoned off.
A spokeswoman for Cambridgeshire Police said: "At this stage details of any injuries are unclear."
The police have urged the public to avoid the area until further notice.
A spokeswoman for the East of England Ambulance Service said: "It appears there are 13 people who are being assessed for injuries at the scene, but it is unknown yet how many need hospital treatment."
At 12.39pm, Cambridgeshire Fire and Rescue tweeted: "We're currently extricating casualties from a car following a collision involving a bus in Peterborough."
The two casualties were successfully rescued by 1pm.
A structural engineer was called to assess severe damage to the building and a gas engineer isolated the mains.
Station Commander Jamie Johnson said: "The emergency services have worked extremely well together to successfully rescue and treat casualties.
"Severe damage has also been caused to a building as a result of the collision."
