BOGOTA, Colombia—A massacre in Colombia attributed to a clash between rival leftist fighters this week shows that armed groups are still wreaking havoc in the country, even after a 2016 peace agreement.
On Oct. 30, six people were killed in a battle that the Colombian army says was between the last standing organized Marxist rebel group, the National Liberation Army (ELN), and dissident members of the demobilized Marxist group Revolutionary Armed Forces of Colombia (FARC).
