Revelers from around the world arrive in Pamplona, Spain, to take part in the San Fermin festival, the eight days of the running of the bulls glorified by Ernest Hemingway's 1926 novel "The Sun Also Rises."

Runners make their way through the street with "El Pilar" fighting bulls as people watch from their balconies during the running of the bulls at the San Fermin festival in Pamplona, Spain, Friday.
The nine-day fiesta — a heady mix of alcohol, daily bull runs, all-night partying and adrenaline — was immortalized in Ernest Hemingway's 1926 novel "The Sun Also Rises."
An American and two Spaniards were gored Friday during a danger-filled sixth bull run of the festival, with one loose bull causing panic in the packed city streets.
Dozens of people are injured each year in the "encierros," as the runs are called in Spanish. Most are hurt after tripping and falling in the rush.
The fighting bulls used in the centuries-old fiesta can weigh up to 1,380 pounds and have killed 15 people since record-keeping began in 1924.
