A Million Join Pamplona's Annual Bull-Running Festival
Visitors from around the world kick off the festival with a messy party in Pamplona, before the eight days of the running of the bulls.
Jubilant crowds filled Pamplona's main square on July 6, 2016 as the traditional "Chupinazo", a firecracker in the shape of a rocket, burst into the sky, marking the beginning of the northern Spanish city's week-long San Fermin festival.
The annual Fiesta de San Fermin, made famous by the 1926 novel of US writer Ernest Hemmingway entitled 'The Sun Also Rises', involves the daily running of the bulls through the historic heart of Pamplona to the bull ring.
Fuente Ymbro fighting bulls take the Estafeta corner during the first running of the bulls at the San Fermin festival in Pamplona, on July 7.
Daredevils test their speed and bravery by racing with six fighting bulls along a half-mile long street course to the city's bull ring. The bulls then face matadors and almost certain death in afternoon bullfights.
Crowds run with Fuente Ymbro's fighting bulls along Estafeta Street during the second day of the San Fermin Running of the Bulls festival on July 7.
Bull runs, or "encierros," as they are called in Spanish, are a traditional part of summer festivals across Spain. Dozens of people are injured each year in the runs, most of them in falls.

Thousands of people waving the festival's traditional red neckerchief jammed the square down below and immediately began jumping and screaming "Viva San Fermin!"n after the 'chupinazo.'
The firecracker also signaled the moment to don the neckscarf, part of the festival garb along with white trousers and shirt.
A wounded runner is moved to be treated after the first bull run of San Fermin on July 7. At least four people were injured during the bull run. Thursday's run lasted 2 minutes, 28 seconds.
Many people suffered falls and were trampled on by the beasts or other runners. In one incident, four bulls crashed into a bunch of participants close to the end of the race, and several people narrowly missed being gored.
