Two people suffered minor injuries but none were gored on Monday on the fourth day of the San Fermin festival where a dozen bulls chase hundreds of people dressed in white with red neckerchiefs through the streets of Pamplona in northern Spain.
Thousands of tourists come from all over the world to run alongside locals, making San Fermin the most famous of the festivals involving bulls that take place across Spain during the summer months.
The festival has religious origins, dating back to the Middle Ages. Participants still chant to an image of San Fermin and ask for his blessing before the run, that starts at 8 o'clock and lasts from 3 to 5 minutes.
Once all the bulls have safely entered the corral inside the town's bullring, the run is over.
