Thousands of runners dashed ahead of six charging bulls Thursday for the first running of the bulls in this year's San Fermin festival in the Spanish city of Pamplona.
No one was gored, but at least one person was treated at a hospital for injuries.
Most runners wore all white and red kerchiefs around their necks during the sprint, which lasted less three minutes.
The street festival was popularized in the 1926 Ernest Hemingway novel "The Sun Also Rises".
The festival continues until July 14.
