A young girl makes a “tomato angel” on a tomato covered street during the traditional tomato fight “Tomatina” during the fiestas in Bunol, Spain, 28 August 2013. This year's Tomatina is the first pay festival after Bunol's City Hall sold 15,000 tickets to take part in the tomato throwing. A total of 20,000 people, including 5,000 residents, will throw over 130,000 kg tomatoes. Local authorities decided to sell tickets this year to avoid the overcrowding in previous years in which over 50,000 people took part in the event. (Photo by Biel Alino/EPA)
