The Toro de Jubilo is an ancient tradition held annually at midnight in the Spanish town of Medinaceli. The event starts when a bull is tied to a post and flammable balls of tar are attached to its horns. Mud is caked on its face and back to protect it from the flames. The tar balls are then set alight, the bull released, and revelers dodge the animal until the flammable material burns out and fireworks are set off. This year's event was delayed when animal rights activists occupied the bullring in Medinaceli. The protesters were removed by police officers, and the Toro de Jubilo proceeded as planned. Gathered here are scenes from this year's event, with a few photos from last year as well.
