A man falls to the ground as he takes part in the annual tomato fight, known as "Tomatina" in Bunol, eastern Spain, on Aug. 31.
Some 160 tons of tomatoes were offloaded from six trucks. As the trucks pulled into the narrow streets, the revelers chanted, "Tomato! Tomato!"
To avoid injuries, revelers are instructed to squelch the tomatoes before throwing them.
The hour-long battle attracts around 20,000 participants, many of them foreigners.
The paid-entry event was inspired by a 1945 food fight between local children in the tomato-producing region.

The tomato fight has been a tradition in Bunol since the end of World War Two and has drawn a large international following in recent years.
After the fight, the participants and the town's streets were drenched in a sea of red pulp. Organizers hose the streets down within minutes of the event ending at noon, while participants could use public showers.
