Each morning from July 7-14 thousands of people, many wearing traditional white shirts with red scarves, line the narrow streets of the medieval city to take part in the centuries-old tradition of running with the bulls.
In an 875-metre (950-yard) chase, half a dozen, specially bred aggressive bulls race from their pen along a winding course to the city's bull ring, with some people from the crowd running alongside while trying to dodge horns and stampeding hooves.
The three runners gored by bulls had injuries in the armpit, arm and leg, a medical official told the press.
The bulls are killed in a ring later in the day in front of an audience during a bullfighting show.
