Security concerns have intensified in parts of South America. In Mar del Plata, Argentina, business and civil organizations have urged political leaders to address rising violence, noting that intentional homicides increased by nearly 47% in the first half of 2026 compared to the previous year. Data from the Municipal Center for Strategic Crime Analysis (CeMAED) also indicated a 31% rise in robberies and thefts against businesses during the second quarter of 2026.

In Antofagasta, Chile, the government has initiated citizen dialogues to implement the Agenda Against Organized Crime and Terrorism (ACOT). This program, supported by the administration of President José Antonio Kast, seeks to engage social organizations and neighborhood councils to discuss security priorities, including strengthening police capabilities and combating criminal organizations.
