Colombia's ELN guerrilla group announced a three-day lockdown and military exercises starting Sunday in its controlled territories, citing perceived intervention threats from the United States.This action follows Donald Trump's warnings last week of military intervention against cocaine-producing countries and the seizure of a Venezuelan oil tanker earlier this week.Reports indicate the ELN is expanding its influence in Venezuela, with its presence in one-third of Venezuelan states now linked to Nicolás Maduro's political survival, though Maduro denies an alliance.
