Tens of thousands of people gather in Bunol on the last Wednesday of August each year for the mother of all food fights.

The fight is thought to have its beginnings in a food fight between children during a parade in the mid-1940s.

More than 100,000 kilograms of over-ripe tomatoes are thrown throughout the streets during this festival.

And while the official rules state the ammunition must be squashed before launch, this rule is not strictly observed.
