Mexicans rally outside Chihuahua state prosecutor's office in Ciudad Juarez, on the country's border with the US, on the International Day of the Disappeared. Mexico has registered more than 100,000 disappearances since 2006, most attributed to criminal organizations. "This day shouldn't exist, but it does and so we have to be here in the struggle so that the authorities do something about it," says one protester. IMAGES AND SOUNDBITES
