Mexican poet Javier Sicilia listens to a female victim of violence after the arrival of a peace caravan in Monterrey June 7, 2011. Hundreds of Mexicans began a week-long procession through Mexico on Saturday to protest the country's bloody drug war, led by Sicilia, a crusading poet whose son was murdered by suspected cartel hitmen. Human rights activists and families of victims of violence formed a peace caravan and piled into 13 buses and more than two dozen cars to set out on a 12-state tour that will end in Ciudad Juarez, Mexico's most violent drug war city on the U.S. border.
