Pope Francis ordered his convoy to stop on Thursday after a mounted police officer was thrown from the horse as the popemobile passed.
The papal convoy stopped abruptly and Pope Francis could be seen disembarking and walking toward the scene where the police officer was lying on the ground.
An ambulance arrived on the scene and took the police officer away and Pope Francis resumed his tour.
It was not clear if the police officer sustained any significant injuries.
