pbr Spectators ran for their lives after a bull jumped into the stands at a bullring in northern Spain injuring at least 30 people.br ppbr The terrifying incident happened in Tafalla, in the northern region of Navarra on Wednesday. The animal leapt over the fence and climbed up the stairs of the stands knocking over people, including young children.br ppbr A 10-year-old boy was in a serious condition with stomach wounds while another spectator was gored in the back, according to reports.br ppbr The incident occurred during a contest of "recortadores" when brave participants attempt to dodge the bull as it runs frantically around the arena. Spectators and officials later tied a rope around the bull to get it under control. The animal was removed from the arena by a crane and later killed.br ppbr It is extremely rare for a bull to jump over a security barrier and into the crowd.br ppbr The incident comes at a time when the country is split over whether bullfighting should be completely outlawed. Last month Catalonia became the first major Spanish region to ban the deadly sport after heated debate that pitted animal rights against a pillar of traditional culture.br ppbr The ban will take effect from 2012 in the northeastern coastal region whose capital is Barcelona.
