A reveler falls to the ground today during the San Fermin bull run in Pamplona, Spain. A man was gored to death today at Pamplona's running of the bulls, the first such fatality in nearly 15 years, and nine others were injured.

PAMPLONA, Spain — A charging bull gored a young Spanish man to death today at Pamplona's San Fermin festival, the first such fatality in nearly 15 years. Nine others were injured in a particularly dangerous and chaotic chapter of the running of the bulls.

Pamplona officials identified the man as Daniel Jimeno Romero, 27, from the Madrid suburbs of Alcala de Henares. He was on vacation with his parents and girlfriend, who identified him.

The San Fermin festival Web site said Jimeno Romero was gored in the neck and lung during a run in which a rogue bull named Cappuccino separated from the pack, which is among the worst things that can happen at Spain's most popular fiesta.

Isolated bulls are more likely to get disoriented and start charging at people.

Photographs showed Jimeno Romero lying on a stretcher moments after the goring, his face and neck stained with blood and his eyes only half-open. An emergency medical worker was leaning over him, applying what appeared to be gauze to his neck wound.

Three other people were gored, and six people suffered bumps, bruises and other lesser injuries, said Fernando Boneta, director of Virgen del Camino Hospital. The festival ends Tuesday, and there was no indication the remaining bull runs would be canceled because of the death.

The last fatal goring at the running of the bulls was that of 22-year-old American Matthew Tassio in 1995. In 2003, a 63-year-old Spanish man, Fermin Etxeberri, was trampled in the head by a bull and died after spending months in a coma.

Today's death raises to 15 the toll since record-keeping began in 1924.

Fatalities are relatively rare, and when one occurs, it serves as a reminder that amid all the street parties and revelry associated with San Fermin, running with fighting bulls weighing 1,300 pounds or more on cobblestone streets packed with people is a life-risking exercise.

This run, the fourth of eight held at San Fermin, was by far the most perilous of this year's festival. The previous three runs were comparatively placid affairs, with no serious injuries.

The six bulls covering the half-mile course with six accompanying steers tend to mind their own business and keep running as long as they stay in a pack. A bull that gets separated is more likely to get frightened and aggressive, and that is what happened today.

Cappuccino, a brown, 1,130-pound specimen, fell early in the run and ended up on its own.

When it reached a stretch right outside the bullring that marks the end of the course, it started charging right and left and even ran back the wrong way several times. Runners scurried for safety to wooden barriers along the route as the bull attacked. Herders waving sticks tried in vain to guide it into the ring, even yanking on the animal's tail to turn it around.
