FARC guerrillas and supporters celebrate at a concert at the 10th Guerrilla Conference in the remote Yari plains where the peace accord was in the process of being ratified by the FARC on September 21, 2016 in El Diamante, Colombia. The peace agreement attempts to end the 52-year-old guerrilla war between the FARC and the state, the longest-running armed conflict in the Americas which left 220,000 dead. The final agreement is set to be signed on September 26 and will then be put to vote by the public in a referendum on October 2. The plan calls for a disarmament and re-integration of most of the estimated 7,000 FARC fighters. (Photo by Carlos Martinez/NurPhoto via Getty Images)
