Members of the group "Heroes of the Homeland," which brings together policemen and soldiers victims of the Colombian armed conflict, march to show their support to the peace process between the government and the FARC leftist guerrilla, in Cali, Valle del Cauca deparment, Colombia, on August 30, 2016. Colombian president Juan Manuel Santos signed a decree Tuesday setting out the question -- "Do you support the final accord to end the conflict and build a stable and lasting peace?" -- voters will answer in the decisive referendum on the peace deal. The peace deal concluded last Wednesday between government and rebel negotiators in Cuba will only be ratified if on October 2 more Colombians answer "yes" than "no," and if the "yes" camp passes the threshold of 4.4 million votes -- 13 percent of the electorate. / AFP PHOTO / Ernesto GUZMAN JR
