Colombia’s National Liberation Army, or ELN, is preparing for renewed fighting as President Abelardo de la Espriella takes office promising a tougher military campaign against armed groups. The ELN, Colombia’s last major left-wing guerrilla organisation, remains active in remote regions and draws revenue from illegal mining and other activities. De la Espriella has said he will end the previous peace approach and confront armed groups, raising fears that the long-running conflict could intensify again.
