The UN envoy for Colombia called Wednesday for improved protection for former combatants who continue to be killed “in alarming numbers,” and he complained of rising violence and massacres by other groups that have cropped up since the 2016 peace accord. Carlos Ruiz Massieu told the UN Security Council that efforts must also be stepped up to fight impunity for these crimes, “including by bringing intellectual authors to justice.” “Priority should be given to staffing and resources for the National Protection Unit to clear the backlog of pending requests for protection for former combatants,” he said. Secretary-General Antonio Guterres´ latest report to the council, circulated last week, said the U.N. political mission in Colombia verified 19 killings of former combatants from the country´s main rebel group, the Revolutionary Armed Forces of Colombia (FARC), in the three-month period ending Sept. 25. The latest victims included one of the highest-ranking former FARC commanders, Jorge Iván Ramos, who became a FARC political party leader and was killed Aug. 28. The U.N. chief said Ramos was actively engaged in implementing the 2016 peace deal with the government, including working on a crop substitution program and the handover process for FARC assets. The FARC party addressed an open letter to the National Liberation Army, known by its Spanish acronym ELN, which is one of Colombia´s last remaining rebel groups, expressing shock “over information that ELN was behind the crime,” Guterres said. He said the latest killings bring the total number of former combatants killed so far this year to 50, including two women. Since the peace agreement was signed, he said, the U.N. mission has verified 297 attacks on former FARC fighters, including 224 killings, 20 disappearances and 53 attempted homicides. Before the peace deal was signed with the FARC, more than 50 years of war in Colombia caused over 220,000 deaths and displaced nearly 6 million people. An amnesty law was adopted covering most offenses committed by FARC fighters. Ruiz Massieu told the Security Council that the FARC’s laying down of arms and its transition into a political party has been completed and is “irreversible.”
