Bolivia's government expelled Colombia's ambassador to La Paz on Wednesday, accusing President Gustavo Petro of interfering in its internal affairs after he described ongoing Bolivian protests as a 'popular insurrection.' The diplomatic escalation marks a shift from Bolivia's domestic political crisis—now in its 15th day—into a regional confrontation, with La Paz filing a complaint with the Organization of American States while receiving support from the United States and other regional governments.
