The killing of CJNG leader Nemesio "El Mencho" Oseguera Cervantes in a Mexican military operation on February 22 is the most significant cartel leadership takedown in years and has triggered immediate, multi-state violence across Mexico — including highway blockades, arson, and armed confrontations in at least eight states. CJNG's succession crisis will drive elevated violence for weeks to months as factions compete for control. Colombia's ELN has declared a unilateral ceasefire ahead of March congressional elections, but pre-election violence against candidates is already well underway.
CJNG leader Nemesio Rubén Oseguera Cervantes, known as 'El Mencho,' died on February 22 after being wounded in a Mexican special forces raid in Tapalpa, Jalisco state. Four CJNG members were killed in the raid itself; two others died during transfer to Mexico City, per Mexico's Defense Secretariat (SEDENA). Oseguera was 59 and had a $15 million U.S. reward on his head.
The operation was supported by the Joint Interagency Task Force-Counter Cartel, a U.S. military-led group quietly launched in January 2026 to map cartel networks on both sides of the border, Reuters reported. U.S. officials stressed the raid was Mexican-led; American forces provided intelligence only. The Guardian separately reported El Mencho was tracked in part through surveillance of a romantic partner.
Violence erupted within hours across at least eight states, including Jalisco, Michoacán, Guanajuato, Colima, and Nayarit. CJNG gunmen torched vehicles and blocked highways. President Claudia Sheinbaum urged citizens to remain indoors. Mexico deployed 2,500 additional troops in the immediate aftermath, in addition to the roughly 10,000 National Guard and Army personnel already deployed along the U.S. border.
The U.S. Embassy issued guidance specifically referencing Puerto Vallarta, Newsweek reported, as armed groups moved into resort areas. Puerto Vallarta is a major U.S. and Canadian tourist hub with significant corporate event exposure. The Jalisco airport remained nominally open but ground access was disrupted by highway blockades.
Separately, reports note that Joaquín Guzmán López — son of 'El Chapo' — was freed by Mexican authorities to defuse an earlier Sinaloa faction crisis. The timing of El Mencho's killing coincides, per Justice in Mexico, with a U.S. Supreme Court ruling reverting Mexico tariffs below 10%, removing one lever of bilateral pressure on Sheinbaum to deliver security results.
The ELN declared a unilateral ceasefire on February 23, citing a desire to allow voters to participate 'in liberty' in the March congressional elections, per AP. The statement did not specify an end date for the ceasefire.
Pre-election violence has already been significant. Indigenous Senator Aida Quilcue was kidnapped in the Cauca region earlier this month and released after a military rescue. Two bodyguards of Senator Jairo Castellanos were killed when ELN fighters opened fire on his caravan, per multiple outlet reports from the past 24 hours. The assassination of conservative presidential candidate Miguel Uribe last year continues to cast a shadow over the electoral cycle.
The ELN, FARC dissident factions, and the Gulf Clan (Clan del Golfo) are all flagged by Colombian authorities as active threats to election integrity, per Daily Sabah. Armed group influence has expanded in rural departments under President Gustavo Petro's administration, which had pursued a 'total peace' strategy that has largely stalled.
Gunmen dressed in military uniforms stormed a rural property in Ecuador within the past 20 hours, killing at least 7 people, per The Independent. No group has claimed responsibility as of this writing.
The attack is consistent with a documented pattern of Mexican and Colombian cartel proxies fighting over cocaine trafficking routes and Pacific port access. Elite Ecuadorian police conducted a separate anti-drug operation in the Batalla del Suburbio neighborhood in Guayaquil as recently as January 23, reflecting ongoing pressure on trafficking nodes.
U.S.-Venezuela engagement continued through diplomatic and energy channels. The U.S. Embassy in Caracas confirmed that U.S. envoy Dogu met with the Maduro administration to reiterate Secretary of State Rubio's three-phase framework: stabilization, economic recovery and reconciliation, and transition. Venezuela named Felix Plasencia as its diplomatic representative to Washington.
U.S. Energy Secretary Chris Wright visited Caracas on February 11 to assess Venezuela's oil sector. Despite diplomatic activity, no concrete production or sanctions relief agreement has been announced publicly. Big oil firms remain hesitant without sovereign-backed guarantees, per Capital reporting.
No major breaking incidents in the last 24 hours. The broader regional context — CJNG's collapse and potential cocaine supply chain disruption — has implications for Brazilian trafficking organizations (PCC, CV) that source precursors and finished product through trans-shipment networks linked to CJNG. Analysts will be watching for any downstream effect on Rio and São Paulo criminal markets over the coming weeks.
No discrete breaking incident in the past 24 hours. CJNG's regional network, which had significant presence in Central America as a cocaine and fentanyl transit corridor, is now leaderless. Honduras, particularly the Sula Valley and north coast port of Puerto Cortés, is a key node. Successor violence or a scramble for territorial control by CJNG sub-commanders could affect transit routes within days to weeks.
No new incidents reported in the 24-hour window. The Bukele government's continued mass incarceration strategy under the state of exception has kept MS-13 and Barrio 18 operationally degraded domestically. However, El Salvador remains a transit zone and CJNG's leadership vacuum could shift Central American cartel alliances.
No major new incidents in the last 24 hours. Guatemala City's Interamerican Highway and the Pacific coast corridor remain the primary CJNG transit routes northward. The cartel's sudden leadership vacuum creates near-term uncertainty for Guatemalan trafficking organizations that served as CJNG sub-contractors or paid plaza fees.
No breaking incidents in the 24-hour window. Peru remains the world's second-largest cocaine producer, and its Vraem valley production feeds networks that include CJNG distribution. The cartel's disarray could temporarily disrupt export pricing and routing, creating secondary effects for Peruvian criminal economies.
No new OSINT in the last 24 hours, but the structural situation remains acute. Gang coalition G9 and rival Viv Ansanm continue to control significant portions of Port-au-Prince. The Multinational Security Support Mission (MSS) led by Kenya has had limited effect on gang territorial control. Port-au-Prince airport access remains the primary corporate concern.
CRITICAL. El Mencho killed Feb 22 in Tapalpa, Jalisco. CJNG retaliation violence active across 8+ states. Jalisco and adjacent Pacific coast states under severe ground movement restrictions. Puerto Vallarta under U.S. Embassy shelter-in-place advisory. Multi-week elevated threat environment near-certain.
ELEVATED. ELN unilateral ceasefire declared ahead of March congressional elections, but candidate-directed violence is ongoing. Two bodyguards killed, one senator kidnapped (released) in the past month. Gulf Clan and FARC dissidents also active. Election period increases risk exposure through late March.
HIGH. At least 7 killed in a military-uniform masquerade attack on a rural property in the last 20 hours. Guayaquil remains a high-risk urban environment with ongoing anti-gang operations. Pacific port drug corridor violence is the primary driver.
ELEVATED. Active U.S.-Venezuela diplomatic engagement continues, with energy and political talks underway. No new violence incidents in the past 24 hours. Underlying economic deterioration and security force human rights concerns persist. Corporate operations face sanctions compliance complexity.
CRITICAL. No change from baseline. G9 and Viv Ansanm gang coalitions control large portions of Port-au-Prince. MSS mission has not reversed territorial losses. Corporate duty-of-care posture should reflect extreme risk for any in-country personnel.
ELEVATED. No new incidents in 24 hours. CJNG leadership vacuum creates uncertainty for Central American transit networks passing through the Sula Valley and Puerto Cortés. Monitor for organizational realignment over the next 2–4 weeks.
ELEVATED. No breaking incidents. CJNG sub-contractor networks in Guatemala face an uncertain near-term as the cartel enters a succession crisis. Pacific coast and northern Petén corridor warrant monitoring.
MODERATE. Bukele's mass incarceration policy continues to suppress domestic gang violence. MS-13 and Barrio 18 remain operationally degraded. Transit risk from regional cartel disruption is secondary.
MODERATE. Ortega government maintains political repression posture. No significant security incidents in the 24-hour window. Economic stagnation and arbitrary detention risk for foreign nationals remain baseline concerns.
ELEVATED. Drug transit violence has been increasing along both Pacific and Caribbean coastlines. No new major incidents in the past 24 hours, but CJNG network disruption could affect trafficking dynamics through Costa Rican territory.
ELEVATED. The Darién Gap migration corridor remains a key vector for northbound migration and narco-trafficking. No new major incident in 24 hours. Panama City commercial environment stable.
MODERATE. Economic crisis and fuel shortages continue. No new security incidents reported. U.S. relations remain strained; travel and commercial activity highly restricted for U.S.-linked entities.
MODERATE. No new major incidents. Tourism corridor (Punta Cana, Santo Domingo) unaffected. Gang violence in Santo Domingo's peripheral neighborhoods is a baseline concern, not acute.
ELEVATED. Gang violence in Kingston and Spanish Town remains persistently elevated. No new major incident in 24 hours. The island is a trans-shipment node; CJNG disruption could affect cocaine routing through Jamaican networks.
ELEVATED. Gang-related homicide rate remains one of the highest per capita in the hemisphere. No new major incident in 24 hours. Port of Spain commercial operations stable.
ELEVATED. No new breaking incidents. PCC and CV narco-factions in São Paulo and Rio de Janeiro remain active. CJNG disruption has potential downstream effects on cocaine supply chains. Carnival security posture in Rio and Salvador de Bahia winds down this week.
ELEVATED. No new incidents in 24 hours. Vraem valley coca production and trafficking networks remain active. Political instability under President Boluarte continues; no imminent acute crisis.
MODERATE. Political tensions between Arce and Morales factions continue to simmer ahead of elections. No new security incidents. Cocaine production and transit activity present a baseline trafficking concern.
ELEVATED. Paraguay remains a significant cocaine transit state. The Tri-Border Area (Ciudad del Este) is a known hub for organized crime. No new major incident in 24 hours.
MODERATE. Buenos Aires commercial environment stable. Milei government economic reforms ongoing. No new security incidents. Rosario drug-gang violence remains a monitored baseline concern.
MODERATE. Santiago commercial environment stable. Northern border areas (Tarapacá, Antofagasta) remain sensitive due to migration and drug smuggling flows. No new incidents in 24 hours.
MODERATE. Montevideo remains the most stable environment in the Southern Cone. No incidents in 24 hours. Port of Montevideo is a cocaine trans-shipment node of increasing regional concern — worth monitoring at the strategic level.
The death of El Mencho is the most operationally significant cartel event since the capture of El Chapo in 2016. But history is instructive here: decapitation strategies in Mexico have repeatedly triggered violence without producing durable security gains. After El Chapo's arrest, the Sinaloa Cartel fragmented into warring factions. CJNG, with its paramilitary structure and geographic breadth, will likely follow a similar trajectory — meaning the next 60 to 90 days are high risk for sustained territorial violence, not a wind-down.
Watch for which CJNG regional commanders move first to claim succession. El Mencho's son, Rubén Oseguera González ("El Menchito"), has been in U.S. custody since 2015, removing the obvious dynastic successor. His brother-in-law, Ricardo Rueda Díaz ("El Doble R"), and other plaza bosses in Zacatecas, Michoacán, and Veracruz are the most likely candidates for a power play. If no single figure consolidates quickly, expect CJNG to fracture into regional sub-groups — a messier but potentially more durable criminal structure that's harder to dismantle.
The U.S. Joint Task Force-Counter Cartel's visible role in the El Mencho operation is a signal that the bilateral security framework has entered a more operationally aggressive phase. Expect the Trump administration to claim this as a validation of its pressure campaign on Sheinbaum, and watch for whether Washington uses this moment to push for additional concessions — extraditions, military basing access, or further border militarization.
Colombia's ELN ceasefire is tactically logical before elections but strategically thin. The ELN has declared election-period ceasefires before and violated them. The more important variable is what happens after the March vote: if Petro's "total peace" process collapses entirely, the ELN has no incentive to hold any ceasefire posture.
Five items to watch over the next 72 hours: (1) Which CJNG plaza boss makes the first public claim to succession; (2) Whether Mexican highway blockades in Jalisco and Colima persist beyond 48 hours, signaling organized resistance versus spontaneous reaction; (3) U.S. Embassy Mexico advisory status — escalation to "do not travel" for Jalisco would be a significant threshold; (4) ELN ceasefire violations ahead of Colombia's March elections; (5) Any Ecuadorian government attribution of the rural 7-fatality attack — if linked to a specific cartel, it will clarify whether this is a new front or continuation of existing territorial fighting.
