Colombia’s government moved to officially end talks with some of the nation’s armed rebel groups, effectively halting the peace process that began under former President Gustavo Petro. President Abelardo de la Espriella’s administration issued a series of resolutions to formally stop the negotiation process with the groups, local outlet El Tiempo reported Saturday. That puts an end to official dialogue between Colombia and major illegal groups including the CNEB, the group known by alias Calarcá and a group that operates in the Sierra Nevada mountain range, it.
