One person was gored in the behind by a bull as hundreds of people took part in the fifth running of the bulls Wednesday in Pamplona's San Fermin festival.
The man, a 31-year-old Spaniard, was treated for a horn wound in the left buttock after one of the bulls tossed him in the air and then pinned him on the ground just seconds before the end of the run, the regional government of Navarra said on its Web site.

Three other Spaniards were treated for light injuries suffered in falls during the event, the government said in the official report of the bull run.
The fifth run was relatively clean and fast, lasting just over three minutes. The bulls remained in a pack for most of the route until the final yards.
Halfway along, one person got up after falling, only to run straight into an oncoming charging bull.
In the runs, held at 8 a.m., hundreds of enthusiasts, including many foreigners, run alongside six fighting bulls and their guiding steer along a near half-mile-long route to the city's bull ring.
The festival in this northern town, renowned for its all-night street parties, dates back to the late 16th century. It gained worldwide fame in Ernest Hemingway's 1926 novel "The Sun Also Rises."
Since record-keeping began in 1924, 13 people have been killed during the runs, the most recent in 1995.
