A flaming fake bull known as a "Toro de fuego"

A flaming fake bull known as a "Toro de fuego" runs after revelers during the 2015 San Fermin fiestas in Pamplona, Spain, on July 6. Revelers from around the world turned out to kick off the festival with a messy party in the Pamplona town square, one day before the first of eight days of the running of the bulls.
