The arrest of Uruguayan narco Sebastián Marset in Santa Cruz, Bolivia and his rapid extradition to the United States is the biggest law enforcement win in South America in months — a direct product of US-Bolivia intelligence cooperation under the "Shield of the Americas" framework. Cuba is the other headline: Havana has confirmed talks with Washington as an acute economic crisis deepens, a Mexican aid ship arrived in Havana Bay yesterday, and Senate Democrats are already moving to constrain Trump's military options. Meanwhile, Ecuador imposed a nighttime curfew across four key coastal provinces, backed by FBI coordination, as post-El Mencho instability in Mexico's Jalisco continues to disrupt civilian life three weeks on.
Sebastián Marset, a Uruguayan national and one of the most wanted drug traffickers in the Western Hemisphere, was arrested in the early hours of Friday, March 13, in Santa Cruz de la Sierra, Bolivia. The operation — conducted by Bolivia's FELCN and UTOP special forces units — began at 2:30 a.m. local time and extended past 9:00 a.m. Marset was taken alongside several associates described as members of his security detail, at least some of them foreign nationals.
Bolivia immediately extradited Marset to the United States, where the DEA had a $2 million reward posted for his capture. Bolivian President Rodrigo Paz called the arrest 'a turning point in the fight against organized crime' and directly credited US-Bolivia intelligence cooperation through the Shield of the Americas framework. A senior US official echoed that framing, per CNN.
Marset led a transnational cocaine trafficking network with confirmed links to Paraguay's Insfrán Clan, Brazil's PCC, and Italy's 'Ndrangheta, per InSight Crime. He had previously escaped a Bolivian operation in 2023 and was released from a Uruguayan prison in 2018 after the government controversially issued him a new passport — a political scandal that still resonates in Montevideo.
Paraguay's anti-narcotics secretary Jalil Rachid confirmed the capture and noted Marset was 'a primary target not just of Paraguay but of Uruguay, Bolivia, and the United States.' He is also suspected in the 2022 assassination of Paraguayan prosecutor Marcelo Pecci. Uruguay's Interior Ministry separately confirmed the arrest.
Cuba confirmed Thursday that it is engaged in formal talks with the Trump administration, framing the dialogue as an effort to 'determine the willingness of both parties to take concrete actions for the benefit of both peoples' and to identify security cooperation areas, per AP. This is the first official Havana acknowledgment of active negotiations.
The Mexican navy vessel ARM Huasteco arrived in Havana Bay on Friday, March 13, carrying aid dispatched by the Mexican government. President Sheinbaum's government has been one of Washington's most vocal critics on regional policy, and the ship's arrival underscores the humanitarian dimension of Cuba's acute crisis.
Cuba's economic situation is severe. Fuel shortages are paralyzing economic activity, per El País English, and the island is experiencing rolling blackouts. The LA Times reported that political analysts are speculating Trump may pursue a Cuba approach similar to the post-Maduro Venezuela model: leave the political structure nominally intact while pushing for economic opening.
Senate Democrats filed legislation Friday that would prohibit the US from attacking Cuba without congressional authorization, per AP. The move is partly procedural — forcing a Senate vote on Trump's stated 'takeover' language — but signals a domestic political constraint on administration options. Miami's Archbishop also warned publicly against ending Haiti and Cuba TPS designations, citing conditions on the ground.
Ecuador declared a nighttime curfew across four provinces — Guayas, Los Ríos, El Oro, and Santo Domingo de los Tsáchilas — effective as of this week. The measure is being executed jointly by the National Police and the Armed Forces, with FBI operational support, per Infobae. President Noboa described it as a decisive action against criminal groups using these coastal corridors for drug transit.
The same coastal zone saw a fresh armed attack that left six dead and three wounded, per SWI Swissinfo. The incident occurred within the curfew's geographic footprint, suggesting enforcement is not yet suppressing violence.
Ecuador's military also seized a 35-meter narco-submarine loaded with fuel, per Latino News. Security analysts quoted in Diálogo Américas described the vessel as evidence of increasingly sophisticated criminal infrastructure — one requiring specialized naval engineering and a clandestine supply chain for motors and navigation systems.
Human rights organizations are raising alarm about a separate military operation in a rural border community, where residents reported bombings, home burnings, and alleged torture during a recent security sweep, per Infobae. The organizations invoked international humanitarian law obligations, including the principles of distinction and proportionality.
The US Treasury updated Venezuelan sanctions licenses on Friday, expanding waivers to allow increased investment and activity in Venezuela's energy, petrochemical, and electricity sectors, and enabling fertilizer exports to the US, per CBC News and Washington reporting. This is a notable policy shift, coming just weeks after the US was seizing Venezuelan oil tankers.
Venezuelan Vice President Delcy Rodríguez publicly called on Washington to cease sanctions entirely, per Últimas Noticias. Her statement included a direct message to the Venezuelan Armed Forces about the importance of coordination with counterparts on citizen security — a signal that Caracas is trying to manage both the external pressure and internal military loyalty simultaneously.
The broader context: per the LA Times, most of the Chavista political apparatus remains in Caracas and is now cooperating with Washington on oil production and exports, following Maduro's removal and transfer to the US to face drug trafficking charges in January. Venezuela's new leadership is navigating a narrow lane — satisfying US demands while maintaining some domestic legitimacy.
The US Embassy issued a security alert Friday as violence linked to post-El Mencho succession fighting continues across multiple Mexican states, per AOL/AP. The alert is current — this is not residual noise from the February 22 operation. Security forces report ongoing engagements.
Civilian search collectives in Jalisco have suspended field operations due to the security environment following El Mencho's death, per El País México. These groups, which search for missing persons in areas where state forces don't operate, say conditions are too dangerous. Their pause reflects how succession violence is spilling beyond cartel-on-cartel clashes into civilian space.
Security Secretary Omar García Harfuch appeared on US television this week to defend the operation that killed Nemesio Oseguera Cervantes ('El Mencho'), stressing that the mission was planned under military protocols with direct Army and Air Force participation. He separately announced the detention of 'Yair N,' a CJNG-linked cell leader in Villa de Álvarez, Colima, per El País México.
Mexico's preparations for the 2026 FIFA World Cup now have a visible security overlay. A large multi-agency operation called 'Operativo Kukulkán' — coordinated through the presidency — is being built out, per CNN en Español. Cartel violence concerns are shaping discussions about whether playoff games in certain Mexican cities could be relocated, per The Athletic/NYT.
FARC dissident factions used drones with megaphones to issue evacuation threats in the Catatumbo region, forcing at least 161 additional families to flee, per El Espectador. A follow-up message from the dissidents claimed their ultimatum was directed at ELN forces, not civilians — but the displacement is real regardless of stated intent.
A landmine exploded in the rural municipality of La Vega, Cauca, wounding three people. Colombian Army Brigade 29, with Air Force and National Police support, evacuated one of the injured, per the Cauca governor's office. The incident is consistent with ongoing IED use by armed groups in the region.
El Nuevo Siglo reported Friday that the armed conflict has affected 104 schools nationwide, with children unable to attend due to threats, forced displacement, or direct attacks on educational facilities. It's a metric that illustrates how broadly the conflict has bled into civilian infrastructure.
Newly inaugurated President José Antonio Kast signed executive directives this week accelerating border security measures, including drone and thermal camera modernization, biometric controls, and physical barriers at unauthorized crossing points, per El País Chile and CNN en Español. Kast explicitly invoked Trump's endorsement and called for regional cooperation on migration and narco-trafficking.
The directives integrate the Interior, Defense, and Public Security ministries into a unified migration control structure. Kast's campaign pledge to dig a three-meter trench along the northern border — modeled loosely on Trump's border approach — is now in the implementation phase, with formal US support being sought.
Costa Rica's Judicial Investigation Agency (OIJ) detained Glen Rojas Barquero and several family members in raids connected to 'Operation Betrayal,' per The Tico Times. The operation mobilized 1,200 OIJ agents and drew on intelligence sharing with Colombia's National Police, among other partners.
The bust reflects a broader pattern: Costa Rica's OIJ has increasingly positioned itself as a regional counter-narcotics hub, coordinating directly with Colombia and US agencies. The Rojas Barquero network appears to have operated in the coastal zone frequently used as a transshipment corridor.
The US lifted a decades-old military embargo on Guatemala — in place since the 1970s-1996 armed conflict period — shortly after the Shield of the Americas summit in Miami, per Curadas. Guatemala was notably absent from the summit itself.
Defense Minister Henry Sáenz confirmed Guatemala has budgeted approximately $50 million for weapons acquisitions in 2026, with Israel and Colombia as primary suppliers. Purchases include aircraft and equipment. The lifting of the embargo opens the door to direct US arms sales for the first time in roughly 50 years.
A new investigation published in El País documents what it describes as a pattern of torture, custodial deaths, and political persecution inside El Salvador's prison and detention system, with at least 420 deaths recorded under conditions of custody. The report challenges the official security narrative built around Bukele's mass-incarceration model.
The findings are based on ongoing documentation by human rights organizations and represent a growing body of evidence that the headline homicide reduction numbers mask serious abuses. No official response from San Salvador had been issued as of this brief.
HIGH. Post-El Mencho succession violence across multiple states has triggered a US Embassy security alert and forced civilian search collectives in Jalisco to suspend field operations. The operating environment remains volatile three weeks after the February 22 operation, with CJNG factions contesting leadership and the World Cup security apparatus racing to get ahead of the threat.
ELEVATED. The US military embargo lift is a structural shift — Guatemala is now in active arms procurement mode for the first time in decades. Watch for how renewed military resourcing affects both border operations and the domestic political balance between civilian and military institutions.
MODERATE. No significant security incidents in the last 24 hours. Belize remains exposed to spillover from Guatemala's northern corridor but no acute developments today.
ELEVATED. No new developments in this cycle. Ongoing extortion and gang activity in the Sula Valley and Tegucigalpa corridors keep the threat level above baseline. US deportation flows continue to stress reintegration capacity.
ELEVATED. Surface homicide metrics remain low, but credible documentation of 420+ custodial deaths under the state of exception signals a serious and worsening rights situation inside the detention system. International scrutiny is growing.
ELEVATED. No new developments today. The Ortega government's repression of civil society and church continues at a sustained pace. The Miami Archbishop specifically cited Nicaragua as a country where TPS conditions remain unmet.
ELEVATED. Operation Betrayal arrests signal active narco network dismantlement, but also confirm that transnational criminal infrastructure is present and operating in Costa Rican territory. The OIJ is performing well; the threat environment that makes such operations necessary is not improving.
MODERATE. No significant security incidents today. Panama continues to manage its role as a transit corridor. The COSCO port services situation at Pacific ports is a commercial rather than security issue at this stage.
HIGH. Drone-megaphone displacement operations in Catatumbo, fresh landmine casualties in Cauca, and 104 conflict-affected schools signal that armed group activity is broad and persistent. The ELN-FARC dissident competition for territory is generating civilian harm across multiple departments simultaneously.
HIGH. The post-Maduro transition government is cooperating with Washington on oil while Delcy Rodríguez publicly demands sanctions relief. Friday's Treasury license updates suggest a transactional détente is underway, but internal military loyalty and economic collapse remain serious variables. The operating environment for foreign energy companies is improving marginally but remains unpredictable.
HIGH. Active curfew in four provinces, FBI-backed joint military-police operations, a fresh mass-casualty attack on the coast, and a seized 35-meter narco-sub all in the same news cycle. Ecuador is in a sustained crisis posture. Rural border communities are reporting military abuses, adding a human rights dimension to an already complex security picture.
ELEVATED. No acute developments today. Shining Path remnants (VRAEM corridor) and cocaine production in the Huallaga Valley keep Peru at an above-baseline threat level. No new incidents in this cycle.
ELEVATED. The Marset arrest is a major success for President Paz's government and a proof-of-concept for US-Bolivia security cooperation. Watch for cartel retaliation risk in Santa Cruz, where Marset's network had deep roots and operational infrastructure.
ELEVATED. No new security incidents in this cycle. The October 2025 Rio mega-raid and its aftermath continue to shape the security environment in the favelas. PCC's transnational reach — now confirmed through the Marset network — remains a concern for federal law enforcement.
ELEVATED. Post-Marset arrest, Paraguay's anti-narcotics leadership is publicly crowing about the capture, but the Insfrán Clan and other network nodes that worked with Marset remain at large. The real test is whether Asunción can roll up those connections before they reconstitute under new leadership.
MODERATE. The Marset arrest closes a significant chapter for Uruguayan law enforcement, which has been embarrassed by the 2018 passport scandal and his repeated escapes. Domestically, security pressure should ease marginally, but Montevideo will face scrutiny over how Marset built his network from inside a Uruguayan prison.
MODERATE. No significant security incidents today. Argentina is subject to a new US Section 301 forced-labor trade investigation alongside Brazil and Chile, which has commercial implications but is not a security matter in the near term. The government's alignment with Washington on regional security policy continues.
ELEVATED. Kast's border security directives are now in early implementation. The northern border with Bolivia and Peru — a major irregular migration and drug corridor — is the focal point. Integration of Defense and Interior ministries into migration control is a structural change that will take months to operationalize but signals clear policy direction.
CRITICAL. Active US-Cuba negotiations confirmed, a Mexican aid ship in Havana Bay, fuel shortages paralyzing the economy, and US Senate legislation to constrain military action — Cuba is in the most fluid political moment it has seen in decades. The risk of rapid, destabilizing political change is real. Assess all Cuba-linked operations and travel at the highest caution level.
CRITICAL. No new developments in this cycle, but baseline conditions remain catastrophic. Gang control over Port-au-Prince and surrounding areas is unchanged. Over 5.7 million people faced famine conditions in 2024 per UN data. TPS protections for Haitian nationals in the US are under active political threat, which could generate a return migration spike the country cannot absorb.
MODERATE. Serving as a transit point for tourists evacuating Cuba via Portugal, per Portuguese government advisories. The DR continues to resist UN pressure on Haiti deportations. No domestic security incidents in this cycle.
MODERATE. No significant security developments today. Oil sector growth continues to attract foreign investment but also organized crime interest. Regional spillover from Venezuela remains the primary external threat vector.
The Marset arrest is a genuinely significant law enforcement win, but the more important story is what happens next in Santa Cruz. Marset's network didn't disappear when he did — the Insfrán Clan in Paraguay, the PCC nodes in Brazil, and the Italian 'Ndrangheta connections are all still functional. Someone will move to fill his coordination role within weeks, probably already has. Bolivia's President Paz is riding high right now, but his government needs to move fast to roll up the secondary network before it reconstitutes. Watch for cartel retaliation in Santa Cruz specifically — Marset's crew will not go quietly, and the city is already a contested criminal marketplace.
Cuba is the wildcard of the next 30 days. The confirmed US-Cuba talks, the Venezuelan precedent (Maduro out, Chavistas cooperating), and the economic collapse create a scenario where the Cuban government accepts a dramatic political bargain faster than anyone expects. The question is whether the Cuban military — which controls the economy — sees more upside in a deal or in holding out. The Kast model in Chile offers a regional data point: right-leaning governments are betting their political identities on Washington alignment right now, which creates space for Trump to extract concessions. Havana is watching Caracas closely.
Ecuador's curfew is being executed in the exact provinces that form the primary cocaine export corridor to the Pacific. If the operations are effective, expect criminal groups to push volume through alternative routes — Peru's northern coast and Colombia's Nariño department are the most logical pressure-release valves. Neither is well-positioned to absorb that traffic without spiking their own violence numbers. The narco-sub seizure is also worth watching as a data point: a 35-meter vessel requires serious capital and engineering expertise, which suggests the transnational networks operating in Ecuador are better resourced than the gang-level framing often implies.
The Guatemala arms embargo lift is flying under the radar but deserves attention. A Guatemalan military with $50M in fresh procurement, Israeli and Colombian weapons suppliers, and no US restrictions is a different actor than the institution that has operated under that constraint for 50 years. How President Arévalo manages civil-military relations as the military gains resources and prestige from the Shield of the Americas alignment is a slow-burn governance risk worth tracking through 2026.
