PAMPLONA, Spain — The penultimate bull run of Spain's San Fermin festival left at least 23 people injured today, when thrill-seekers fleeing the beasts were crushed at the narrow entrance to the bullring, officials said. Two of the injuries were gorings.
As the huge animals thundered into the entrance of the tunnel, they were blocked by a mound of dozens of people who had fallen and were piled on top of one other.
One bull that had fallen before the entrance got up and charged into the clogged passageway. Two steers jumped over the pile of people as they began to get up and flee.
A gate normally used to let regional police into ringside positions was pushed wide open by a flood of runners, causing an obstruction for others trying to enter the main arena, Interior Ministry regional spokesman Javier Morras said.
"We all know that alley is a funnel and a critically dangerous point at the entrance to the ring," Morras said. "Pileups there are one of the biggest risks that can occur in the running of the bulls," he said.
The blockage ended after attendants managed to let the beasts escape through a side door normally reserved for matadors.
Javier Sesma, a health spokesman for Navarra province, said two of the 23 injured people were gored by bulls and that the others were hurt in the stampede.
Sesma said one runner, a 19-year-old Spaniard from Vitoria city, was seriously injured when his thorax was crushed at the bull ring entrance. An Irish citizen also suffered asphyxia.
"His situation remains very grave, but he appears to be evolving favorably," Sesma said of the Spaniard. "We are hopeful. His life was at risk, but he is now more stable."
One person was gored in his buttock and another in an armpit during the 928-yard (850-meter) dash through Pamplona's narrow streets, the official said. Neither injury was serious, said the Navarra government, which organizes the annual festivities. One of those gored had received treatment in one of the two operating rooms at the bullring, Sesma said.
The rest of the injured sustained cuts and bruises.
Sesma said one spectator had a heart attack while watching the stampede. By early afternoon, nine of the injured had been discharged from hospitalization, Sesma said.
On Friday, the festival drew widespread attention when an American college student and two Spaniards were gored, and videos and photos of the attacks were seen around the world. Sesma said the American patient was "evolving favorably" in a hospital today.
The number of revelers attending the festival tends to swell at weekends, causing the narrow streets of Pamplona to be thronged with runners, increasing the risk of pileups and injuries.
The festival in this northern city dates back to the late 16th century and also is known for its all-night street parties.
The runs, eight in all, are the highlight of a nine-day street festival to honor Pamplona's patron saint, San Fermin.
Each morning, six fighting bulls and six bell-tinkling steers that try to keep the beasts together head from stables to the ring where matadors will star in late afternoon bullfights.
The festivities, which end Sunday, were made famous by Ernest Hemingway's 1926 novel "The Sun Also Rises."
The fiesta attracts tens of thousands of young people, many from abroad, eager to mix alcohol with the adrenaline of running alongside the massive bulls at 8 o'clock every morning.
Dozens of people are injured each year, with gorings often producing the most dramatic injuries.
The last fatal goring happened in 2009.
