A farmer of the "400 Pueblos" organization, wearing a diaper and an image of the capital's former Mayor Marcelo Ebrard, faces two cars during the group's annual march, in Mexico City, earlier today. The group protest in their underwear and sometimes naked because they say it is the only way to get attention. The mostly poor farmers of Mexico's southern states, who fight for land rights, aimed this year's march at the former mayor and police chief, alleging they suffered repression and discrimination in last year's march.
