Latin America Daily Security Brief

The USS Nimitz carrier strike group arrived in the Caribbean this week, confirmed by Military Times, as Washington's posture toward Havana hardened sharply. The deployment follows the DOJ's criminal indictment of former Cuban president Raúl Castro on charges related to the 1996 shootdown of two civilian aircraft that killed three Americans and one permanent U.S. resident.

President Trump said Thursday he would be 'happy' to order military action against Cuba. Secretary of State Marco Rubio, speaking separately, called Cuba a 'national security threat' and said the likelihood of a diplomatic resolution — given ongoing CIA and State Department talks in Havana — is 'not high.' Rubio also accused Cuba of being 'one of the leading sponsors of terrorism in the entire region.'

The humanitarian situation on the island is deteriorating in parallel with the political crisis. El País English reports Cuba is now experiencing more hours without electricity than with it, a consequence of the effective U.S. blockade on oil supplies. Aid organizations are describing conditions as a 'tipping point,' with cascading failures in food and water access tied directly to the power crisis.

Havana accepted €86 million in EU humanitarian aid as the crisis deepens, and the Cuban government has publicly framed the standoff as a siege rather than a diplomatic dispute — mobilizing over five million citizens on May Day under the slogan 'la patria se defiende.' The regime's internal security apparatus remains intact for now, but analysts cited by CNBC warn that prolonged blackouts could destabilize state control in ways that force improvised responses from both sides.

The Castro indictment is widely read as a delegitimization strategy rather than a precursor to imminent military action — the Atlantic Council frames the U.S. goal as creating 'conditions for internal change' rather than a direct overthrow. Still, with a carrier group in theater and Trump making public statements about intervention, the risk of miscalculation is real and elevated.

Both the ELN and the Central General Staff (Estado Mayor Central, EMC) — the largest FARC dissident faction — announced separate ceasefires ahead of the May 31 presidential election. The ELN's pause runs from midnight May 30 to midnight June 2; the EMC's nationwide suspension of operations against public forces covers May 20 through June 10. Reuters and multiple Colombian outlets confirmed both announcements Wednesday.

The campaign has been the deadliest in decades. DW reported the attempted kidnapping of ruling-party Senator Alexander López on a southwestern highway this week, with President Petro blaming a drug-trafficking armed group. A senator, Miguel Uribe Turbay, was shot in the head at a campaign event last year. InSight Crime flagged the election as one of three stories shaping regional organized crime this week.

Colombian military forces killed six members of the Ismael Ruiz structure, part of the Bloque Isaías Pardo (faction 'Mordisco'), in a rural area of Belalcázar, Cauca. Separately, a Colombian army strike hit the security commission protecting the ELN's top command (COCE and DINAL) during movement between Venezuela and Colombia — details reported by Infobae. Both operations point to continued military pressure even as political ceasefires are announced.

The ELN released new proof-of-life communications from four hostages — police officers and prosecutors' office agents seized in Arauca in May and June 2025 — to their families. The release of materials is being read as a confidence-building gesture ahead of the election rather than a prelude to their release.

Sixty-one social leaders have been killed in Colombia so far in 2026, according to El Nuevo Siglo. InSight Crime also flagged the Clan del Golfo's reported plans to move approximately 500 fighters toward two designated demobilization zones (ZUTs) in Tierralta, Córdoba, and Nuevo Belén de Bajirá, Chocó — a significant potential development in that group's relationship with the state.

Venezuela's energy diplomacy is accelerating on multiple fronts. Rubio confirmed Thursday that acting President Delcy Rodríguez will travel to India next week to discuss oil sales. The Times of India reports Venezuela has already become India's third-largest crude supplier in May, as Indian refiners diversify away from Hormuz-route oil amid the ongoing Strait closure.

U.S. Energy Secretary Chris Wright has met with Rodríguez, and U.S. attorneys and consultants have traveled to survey Venezuelan oil fields, per WPLG Local 10. A temporary U.S. Embassy office is operating on the top floor of a Caracas hotel while the official compound undergoes renovation — the building sat empty for seven years. The optics of that detail tell the story of how fast the bilateral relationship has moved.

InSight Crime published a substantive assessment this week asking whether Venezuela is actually fighting organized crime or performing the effort for its U.S. overseers. Their analysis: Rodríguez is walking a narrow line between Washington's demands and the criminal alliances — including the Cartel of the Suns and ELN — that have sustained chavismo's political control for years.

Bolivia's protest crisis, now in its third week, escalated sharply. Miners, transport workers, labor unions, and Indigenous groups are maintaining nationwide blockades and strikes against President Rodrigo Paz's centrist government, driven by economic pressures, fuel shortages, and political opposition led by former president Evo Morales. The Guardian and Reuters both covered the crisis Wednesday.

President Paz announced a cabinet reshuffle and the creation of a new advisory council for Indigenous groups and workers — while simultaneously refusing to 'dialogue with vandals.' The U.S. has formally characterized the unrest as 'an ongoing coup d'état' against Paz Pereira, who restored relations with Washington after taking office in November.

The diplomatic fallout widened Thursday when Paz ordered the immediate expulsion of Colombia's ambassador in La Paz, in retaliation for public statements by Colombian President Gustavo Petro about the Bolivian crisis. Petro's comments were characteristically blunt; Paz's response was equally swift.

Cross-border commercial impact is now measurable. Infobae reports more than 1,000 trucks are stranded at the Peru-Bolivia border on the Puno-Desaguadero route. Peruvian authorities have not released official figures on citizen returns from Bolivia.

At least 25 people were killed in two separate organized crime attacks in Honduras on May 21-22. The larger incident was a massacre in the Bajo Aguán region of Colón — an area with a long history of land disputes, drug trafficking, and armed group activity. The Honduran government announced an immediate intervention deploying a combined team of prosecutors, military, judges, and intelligence agents to the zone.

Separately, four police officers and one civilian were killed in Omoa, Cortés — a border municipality with Guatemala — when an anti-gang unit clashed with suspected narco-traffickers. National Police confirmed the deaths on social media.

The timing is notable: both attacks occurred within days of the Honduran Congress passing security reforms that authorize military participation in public security, create a new organized crime division, and allow the government to classify gangs and drug cartels as terrorist organizations. Security Minister Gerzon Velásquez said the government will not allow the crimes to go unpunished.

OFAC sanctioned more than a dozen individuals and entities across two Sinaloa Cartel financial networks on May 20-21. The first network, led by Armando de Jesús Ojeda Avilés, launders fentanyl proceeds through cryptocurrency. The second, run by fugitive Jesús González Penuelas, is a major fentanyl distributor with its own money-laundering arm. Treasury Secretary Scott Bessent framed the action as part of a broader counter-narcoterrorism campaign.

Mexican Navy (SEMAR) dismantled three clandestine labs in Sinaloa state, seizing approximately 4,000 kilograms of methamphetamine, 4,500 liters of liquid precursors, and 200 kilograms of other substances and chemicals. The government estimated economic damage to criminal organizations at over 923 million pesos. The operations are separate from the OFAC actions but reinforce a pattern of coordinated bilateral pressure.

The U.S. Africa Command chief, General Dagvin Anderson, told the U.S. Congress that both CJNG and the Sinaloa Cartel have established methamphetamine labs in Africa to exploit permissive regulatory environments and expand into Middle Eastern and African markets. El Financiero first reported the congressional testimony.

A U.S. security delegation met with President Claudia Sheinbaum at the National Palace on May 21, per Infobae. No agenda was published, but the meeting coincides with the OFAC sanctions rollout and ongoing questions about CIA operational involvement following the Sierra Tarahumara operation in April — Chihuahua's governor denied authorizing CIA participation in that operation while defending coordination with Washington on narco-trafficking.

Panama President José Raúl Mulino ordered the immediate, indefinite suspension of electricity sales to Costa Rica on May 21. The move is a direct retaliation against new Costa Rican President Laura Fernández, who took office May 8 and has publicly demanded 'international actions' to force Panama to comply with a 2024 WTO ruling that found Panama's import restrictions on Costa Rican goods to be inconsistent with its trade obligations.

Costa Rica's state electricity utility ICE responded swiftly, saying Costa Rica is not currently importing power from Panama and has no firm purchase contracts for the rest of 2026. The statement deflated the immediate practical impact of Mulino's announcement, but the diplomatic deterioration is real — the dispute has been active since 2019 and is now being escalated by a newly elected president with a mandate to resolve it.

Panama's position: resolve the trade conflict 'at a table, not in courtrooms.' Costa Rica's position: the WTO already ruled in our favor, and we intend to enforce it. The two governments are now effectively at an impasse, with the dispute now touching energy, trade, and diplomatic relations simultaneously.

President Bernardo Arévalo announced dozens of arrests under an ongoing state of emergency, with police and military forces intensifying patrols targeting street gangs blamed for a surge in violence. AP reported the development on May 21. Guatemala police also captured a Venezuelan and a Spanish national wanted in Spain for homicide — part of a broader 26-arrest extradition sweep so far this year, with 16 of those cases tied to drug trafficking.

The security sweep is notable given Guatemala's role as a transit corridor. Cross-border gang activity from Honduras and Mexico-linked cartel logistics routes both run through Guatemalan territory, and the state of emergency gives Arévalo's government legal cover for more aggressive enforcement.

Diálogo Américas reported coordinated Ecuadorian security operations targeting transnational criminal networks, with particular focus on illegal mining in border regions. Authorities have publicly linked illegal mining to the same criminal networks driving drug trafficking violence — a connection that has become more explicit in official messaging over the past several months.

A joint Peruvian-Ecuadorian operation dismantled a weapons trafficking network that was moving arms from Peru and Ecuador into Colombia. More than 20 people were arrested. Among the groups named in the investigation: Comandos de la Frontera, a structure linked to the Segunda Marquetalia FARC dissident faction operating out of Putumayo, Colombia, into Ecuador, Peru, and Brazil. Infobae reported the operation.

President José Antonio Kast reshuffled his cabinet roughly two months into office, replacing his government spokesperson and the Minister of Security. Kast came to power promising a security 'emergency government,' including border militarization, a migrant wall, and treating cross-border narco-trafficking as a national security offense. The early cabinet changes suggest implementation friction — not a policy reversal, but a sign that his aggressive security agenda is running into execution challenges.

Argentina's northern provinces held a security summit in Tucumán, with ministers from Tucumán, Salta, Jujuy, Catamarca, and Santiago del Estero joining national Security Minister Alejandra Monteoliva to coordinate anti-narco strategy — the first such gathering in decades. The NOA region (Argentina's northwest) is an increasingly active transit corridor for Andean drug flows.

Acting President Delcy Rodríguez traveled to Bolívar state leading a caravan of thousands of motorcyclists, explicitly framing the visit as promoting 'dialogue' — a domestic political signal as much as a policy trip. Bolívar state borders Brazil and sits above Venezuela's most resource-rich mining territory, where informal armed groups tied to organized crime remain active.

InSight Crime's assessment of Venezuelan anti-crime policy, published this week, finds that Rodríguez has taken some visible enforcement steps since Maduro's capture in January, but has not dismantled the structural criminal alliances — including the ELN's cross-border operations and the Cartel of the Suns within the armed forces — that have long been integral to the governing coalition's survival.

Beyond the Panama electricity dispute, Costa Rican authorities disclosed a money-laundering network linked to a drug plane that landed in Chinandega, Nicaragua. The OIJ (judicial police) director connected the network — dubbed the 'Lusso case' — to two prior major trafficking investigations, the Manantiales and Torero cases. The disclosure points to Costa Rica's growing role as a financial layer in Central American drug networks, not just a transit corridor.

A separate investigation found that a criminal organization was importing stolen vehicles from Panama into Costa Rica and selling them as legitimate purchases. The OIJ is the lead investigative agency on both cases.
