There was water fights and wine squirting as the annual festival of the Running of the Bulls got underway in Spain today.
Thousands of revellers, many of them British, donned traditional white outfits and red neckerchiefs for the beginning of the nine-day festival.
The first of eight bull runs is set to begin at 8am local time tomorrow, when thousands of thrill-seekers will try to run alongside six fearsome bulls down a narrow 875-yard course through the city's streets.
Later in the afternoon the bulls will face matadors and be killed in the ring.
Animal rights activists staged protests warning that 48 bulls are killed at the festival, which is known in Spain as San Fermin, each year.
