PAMPLONA, Spain -- Bulls gored two men Saturday in the opening of the annual Pamplona, Spain, bull run made famous by U.S. writer Ernest Hemingway.
One man was gored in the buttocks and another in the shoulder, reported Sky News.
"Injuries have been relatively light," mostly limited to cuts and bruises, said paramedic Jose Aldaba.
The week-long celebration continues through July 14, drawing thousands of tourists from throughout the world each year.
The main event involves runners fleeing bulls as they charge through the streets to a bullring. Injuries are common as the runners try to stay upright and ahead of the bulls in the narrow streets.
Thirteen people have died in the run since 1924, when records began being kept. The last death occurred in 1995 when a 22-year-old U.S. runner was fatally gored.
The festival dates to the 16th century and gained worldwide fame from Hemingway's 1926 novel "The Sun Also Rises."
