Tens of thousands of people flock to the northern Spanish city of Pamplona to take part in the annual Running of the Bulls. The run is held during a nine-day festival of San Fermin, and has been celebrated since 1591. Runners wear red neckties during the event which sees six bulls run each day from the outskirts of the city through the narrow streets into the bullring in the centre of the city - preceded by crowds of revellers. Slips and falls are commonplace as the runners round street corners. Since 1924, more than 14 people have been killed taking part in the event.
