Three people were gored by bulls during celebrations in Pamplona

An American and two Spaniards were gored Monday during one of the famous San Fermin bull runs in Pamplona, ​​northern Spain, which injure dozens each year.

Red Cross worker José Aldaba told Spanish National Television that one man was gored on the street, while two others were pierced by a bull´s horn inside the bullring at the end of the run.

Festival organizers said one of the runners gored was Australian and the other two were Spaniards. None was in serious condition.

The run finishes at Pamplona's bullring, where later in the day the bulls are killed by professional bullfighters.

Tens of thousands of foreign visitors come to the Pamplona festival that was made known to the English-speaking world through Ernest Hemingway's 1926 novel "The Sun Also Rises."

Ernest Hemingway, the Nobel-prize winning American writer, is widely credited for the festival shooting into international fame.

Starting in 1923, San Fermin became an obsession for him, and he visited the festival nine times.
