Graphic footage: Panic at the San Fermin Festival 

Four people have been gored during the sixth bull run of Spain's San Fermin festival, causing panic in the packed streets of Pamplona city. Tensions soared when one bull charged a young man and tossed him around on the ground with its horns for almost 30 seconds as fellow runners tried to pull the beast away by its tail. The helpers eventually dragged the victim to safety by his feet.
