Journalists part in a protest to mark one month since the murder of their colleague Javier Valdez, a noted expert on the country's drug cartels and AFP contributor whose death appears far from being brought to justice- in downtown Mexico City on June 15, 2017. Valdez, 50, was shot a dozen times in broad daylight on May 15 outside the offices of Riodoce, the newspaper he co-founded in the violent western state of Sinaloa. / AFP PHOTO / Pedro Pardo
