Latin America Daily Security Brief

Colombia held the first round of its presidential election on June 1. Conservative-aligned candidate Abelardo de la Espriella won the first round, according to Colombia Reports. Left-wing Senator Iván Cepeda — backed by outgoing President Gustavo Petro — dismissed the preliminary results, claiming fraud concerns. A runoff is now set, most likely between de la Espriella and Cepeda.

Armed groups did not wait for polls to close. Colombia's ombudsman reported at least 48 people killed in clashes between FARC dissident factions in the Guaviare department on or around election day. The ELN separately attacked a military barracks in northern Colombia, according to Colombia Reports. Both incidents confirm that armed actors are treating the political transition as an opportunity, not a constraint.

In a separate military operation, Colombian armed forces launched an airstrike against a Clan del Golfo encampment on the Chocó-Valle del Cauca border on May 31. The target was a substructure linked to alias 'Machín,' according to Cambio Colombia. Ground and air units coordinated the strike — part of an ongoing offensive the military says covers the entire national territory.

In Tolima department, the CTI (Colombia's judicial police) reported possible armed-group pressure on voters during the election — including audio of what appeared to be carnetización orders, forcing residents to show ID cards issued by criminal organizations to move freely. The report noted that Venezuelan nationals living in the area were explicitly exempted from the coercion, per Infobae.

The election's foreign-policy stakes are real. The two right-wing candidates in the race — de la Espriella and Vicky Dávila — have both promised to restore ties with Israel and take a harder line on armed groups, reversing Petro's 'Total Peace' policy. Cepeda's platform centers on continued dialogue. Analysts cited by El Diario Vasco warn that whoever wins inherits a fiscal deficit, a collapsing health system, and criminal structures that Petro's peace process arguably strengthened.

A military operation in Zitácuaro, Michoacán on May 30 triggered cartel-organized narcobloqueos — roadblocks using stolen and burned vehicles — across the municipality starting at 12:30 local time. Infobae and Turquesa News report that trucks, passenger buses, and public transit vehicles were torched to block all exits. State security police and federal forces worked through the evening to clear roads. The Army deployed air force helicopters for reconnaissance and tactical support.

Seven inmates were killed and several injured in a fight at the Aguaruto prison in Culiacán, Sinaloa, on the night of May 31. The prison holds a significant number of cartel-affiliated inmates and has seen recurring violence since the Sinaloa Cartel split between the Chapitos and Mayos factions intensified in late 2024.

A separate armed attack in Los Cabos on the night of May 31 left five civilians and two military personnel wounded, according to Infobae. The Mesa Estatal de Seguridad confirmed a security deployment was activated the morning of June 1. Los Cabos has seen rising cartel violence tied to territorial disputes in Baja California Sur.

Mexican authorities discovered a narcotunnel connecting Tijuana to San Diego's industrial corridor. The tunnel runs roughly 120 meters and includes ventilation and lighting, according to the FGR (federal Attorney General's Office). The structure was used for weapon, explosives, and drug storage and logistics — not just passive transit.

Mexico's Congress moved to prosecute Chihuahua Governor Maru Campos after she publicly refused to expel U.S. agents participating in field operations against cartels. The ruling Morena party is pushing the prosecution. Campos responded by calling on the government to stop normalizing cartel violence, per Infobae. This is the sharpest public confrontation yet over U.S. operational presence inside Mexico.

A CJNG leader described as 'key' was captured by Mexican military forces on June 1, according to MSN citing security sources. No name has been officially confirmed, but the arrest fits the pattern of ongoing operations targeting CJNG's post-El Mencho command structure. Reporte Indigo noted this week that the combined effect of El Mencho's death and El Jardinero's arrest has measurably weakened CJNG's operational coherence in the Jalisco-Michoacán-Nayarit corridor.

Separately, El País reports that at least eight vessels have been interdicted since January 2026 on a new Pacific maritime corridor running between Guatemala and Chiapas, with multiple tons of cocaine seized. Investigations by Mexican and U.S. authorities trace cargo origins to the Ecuadorian coast — a route that organized crime has revived under pressure from intensified land-border enforcement.

AP reported this morning that Chavismo is fracturing. Acting President Delcy Rodríguez is quietly dismantling several Chávez-era economic controls, a move that has drawn internal opposition from hardliners within the ruling PSUV party. The AP piece describes a shift significant enough to create open divisions within the coalition that has governed Venezuela since 2013.

Former opposition candidate Edmundo González publicly called for presidential elections on May 31, marking the five-month point of Rodríguez's interim administration. His statement, per WHEC citing AP, frames the call as a constitutional demand rather than a political negotiation — and signals that the opposition sees a closing window to press for elections while the governing coalition is unstable.

Trump told reporters this week that the U.S. and Venezuela are 'working well together,' per CBS News. U.S.-Venezuela relations have moved fast since the January capture of Maduro — nonstop flights resumed May 1, and Venezuela deported Maduro ally Alex Saab to U.S. custody in May. The trajectory is toward transactional normalization, not a democratic transition.

The top U.S. military commander for Latin America (SOUTHCOM) met with Cuban military leaders near the U.S. naval base at Guantánamo in what AP describes as a 'brief exchange on operational security matters.' The meeting's substance has not been disclosed. It follows weeks of escalating U.S. pressure on Havana.

A U.S. grand jury in Florida indicted former Cuban President Raúl Castro and five others on murder and conspiracy charges related to the 1996 shoot-down of two civilian aircraft operated by Brothers to the Rescue. The indictment's timing — announced this week — is widely read as pressure leverage rather than a realistic extradition scenario.

Defence intelligence firm Janes, cited by the CPA, says U.S. ISR sorties over Cuba have increased measurably since February 2026. Russia has committed to sending a second oil tanker to Cuba after Washington allowed the first to pass through its blockade. The energy crisis on the island remains acute, and Moscow's limited resupply effort is more symbolic than sustaining.

The Trump administration formally designated the PCC (Primeiro Comando da Capital) and the Red Command (Comando Vermelho) as terrorist organizations, per Latin Times. The designation triggers U.S. financial sanctions, bars Americans from transacting with the groups, and enables asset freezes against members. It is the first time either organization has received this classification from any government.

InSight Crime analysts emphasize that both the PCC and CV are profit-driven, not ideological. The PCC was founded in São Paulo prisons in 1993 following the Carandiru massacre and has since expanded across nearly every Brazilian state, as well as into South America, Europe, and Asia. The CV has expanded its territorial presence in Rio's metro region even amid repeated large-scale police operations.

The Al Jazeera 'Rio's Forever War' documentary piece published this week details the aftermath of a police operation that left more than 120 people dead in a single day — described as Brazil's deadliest ever police operation. Police withdrew without securing the scene, a pattern that has drawn sustained criticism from human rights organizations.

President Rodrigo Paz signed legislation on May 31 authorizing military intervention in cases of social unrest, per AP. On the same day, protesters filled the streets of La Paz demanding his resignation. Paz warned demonstrators that those who refuse dialogue will face legal consequences.

The new law is a significant escalation — Bolivia has not had formal legal authorization for military domestic deployment in decades. The political context is a country still managing the fallout from Evo Morales's extended political shadow and deep divisions between highland indigenous movements and the government in La Paz.

Peru's June 7 presidential runoff is one week out. The two remaining candidates are clashing sharply on crime and what one has called a 'political mafia,' per France 24. Mining investment is now a central fault line — the president of Peru's National Mining Society warned this week that opposing mining policies from both candidates could jeopardize billions in investment, per Reuters.

Security has become the dominant campaign issue. Both candidates have made contradictory promises on crime that have spooked the extractive sector, whose operations depend on stable relations with rural communities and functioning state security.

Guatemalan security forces dismantled a criminal network with confirmed links to Mexico following a 48-hour military operation, per El País. Authorities seized weapons, cash, and vehicles. No specific cartel affiliation was named in available reporting, but the operation fits the broader pattern of anti-trafficking pressure along the Pacific corridor.

The U.S. and Guatemala have agreed to 'joint strikes' — meaning U.S. forces can conduct operations against drug trafficking groups inside Guatemalan territory, per Breitbart/Cartel Chronicles citing senior defense and homeland security officials. This is a significant sovereignty concession and a direct parallel to the political storm it has triggered in Mexico.

Honduran and U.S. officials met to explore new joint military operations against organized crime, per a Spanish-language report citing Honduran security official Argueta. The meeting established cooperation frameworks across narcotrafficking, arms trafficking, human trafficking, and cross-border criminal structures.

Honduras is positioning itself — alongside Guatemala — as a willing partner for direct U.S. operational engagement, a contrast to Mexico's current political friction over the same issue.

Foreign ministers and security ministers from Chile, Argentina, Peru, Bolivia, and Ecuador met in Santiago on May 28 to coordinate a regional strategy against transnational organized crime and drug trafficking. The meeting produced a framework agreement, per EFE. Chile's national security adviser Matías Garretón acknowledged publicly that his country lacks tools to directly target criminal economies — a notable admission.

Paraguay's military announced that its 'Cielo Guaraní Soberano' airspace control protocol is forcing drug traffickers to seek alternative smuggling routes. General Julio Fullaondo confirmed the shift in a statement, per La Nación Paraguay. This is consistent with the broader pattern: enforcement pressure in one corridor drives route displacement, not overall volume reduction.

Ecuador's Pacific coast has emerged as the origin point for the new Mexico-Guatemala maritime trafficking corridor, per El País. Seized cargo across at least eight interdicted vessels since January 2026 has been traced back to Ecuadorian ports. A separate multi-country investigation involving the U.S. is tracking a vessel that stopped in Ecuador, Panama, and China — cargo estimated at $697 million, per the same report.

Ecuador was also part of the Santiago security summit with Chile, Argentina, Peru, and Bolivia. The country's inclusion reflects its status as both a transit and production-adjacent node in the cocaine supply chain, and its government's stated interest in multilateral security frameworks following years of escalating cartel violence.

A senior U.S. diplomat traveled to both Haiti and the Dominican Republic for talks on security and economic issues, per AP. The Dominican Republic has been confirmed as a close U.S. partner — President Abinader previously agreed to allow U.S. forces to operate in restricted Caribbean areas.

Haiti's gang crisis continues to define the security environment. No specific new sigacts reported in the last 24 hours, but the diplomatic visit underscores that Washington views the Haiti situation as an ongoing regional destabilizer requiring active management.
