Eleven people were killed during a security operation by the Mexican Navy in the state of Sinaloa on Thursday, March 19, 2026, authorities reported. The operation, targeting a faction of the Sinaloa Cartel known as “Los Mayos,” underscores the ongoing violence plaguing the region as criminal groups vie for control. This latest clash comes amid heightened security alerts ahead of Mexico’s co-hosting of FIFA World Cup matches in June, raising concerns about potential disruptions and further bloodshed.
The operation unfolded across several municipalities in Sinaloa, a state long considered the heartland of the Sinaloa Cartel. According to a statement from the Mexican Security Cabinet, naval personnel responded to an attack from a building used by individuals affiliated with Los Mayos. A subsequent exchange of gunfire resulted in the deaths of 11 suspected criminals, and the seizure of high-powered weaponry. The ongoing conflict within the Sinaloa Cartel stems from the 2024 arrest of Ismael “El Mayo” Zambada, a co-founder of the organization, following his handover to U.S. Authorities by Joaquín Guzmán López, a leader of the rival “Los Chapitos” faction. This power vacuum has ignited a brutal internal struggle for dominance, impacting communities across the state.
Internal Cartel Conflict Fuels Rising Violence
The escalating violence in Sinaloa has resulted in a significant loss of life and widespread displacement. According to data from the Consejo Estatal de Seguridad Pública (CESP), a local public safety NGO, the conflict between Los Chapitos and Los Mayos has caused more than 1,800 deaths and over 2,400 forced disappearances in Sinaloa since September 9, 2024. The U.S. Government declared the Sinaloa Cartel a terrorist group last year, further highlighting the severity of the situation. The recent operation by the Mexican Navy is part of a broader effort to quell the violence and restore order, with 1,600 additional military personnel deployed to the state in January.
During the March 19th operation, authorities similarly briefly detained and subsequently released Mónica Zambada, the daughter of Ismael “El Mayo” Zambada. Local media reports indicate that Zambada was previously included in U.S. Accusations in 2007 regarding alleged involvement in companies used for money laundering, and was sanctioned by Washington in 2019 before being removed from a U.S. Treasury Department sanctions list. Her detention and release underscore the complexities of targeting cartel leadership and their families, even as authorities seek to dismantle their networks.
U.S. Sanctions and Regional Implications
The U.S. Government has taken steps to disrupt the operations of Los Mayos and its associates, including sanctions and asset freezes. These actions aim to cut off the financial lifelines of the cartel and hold individuals accountable for their involvement in criminal activities. The ongoing conflict within the Sinaloa Cartel has broader implications for regional security, as it could lead to increased drug trafficking and spillover violence into neighboring countries. The Mexican government, under President Claudia Sheinbaum, has pledged to address the high homicide rate in Sinaloa, but the recent surge in violence demonstrates the challenges ahead.
The Mexican Navy indicated that it maintains a presence in the area and that the operation is ongoing, with the objective of protecting the population. The incident occurred as Mexico prepares to host matches for the FIFA World Cup, an event expected to draw millions of tourists. Authorities are working to ensure the safety and security of both residents and visitors during the tournament. The situation remains fluid, and further operations are anticipated as the Mexican government continues its efforts to combat organized crime in Sinaloa.
The ongoing struggle for control within the Sinaloa Cartel highlights the enduring challenges of combating drug trafficking and organized crime in Mexico. The conflict between Los Chapitos and Los Mayos, coupled with the recent arrest of key cartel leaders, has created a volatile environment that threatens the stability of the region. The Mexican government’s response, including increased military deployments and international cooperation, will be crucial in mitigating the violence and restoring order.
Authorities have not announced a timeline for the completion of the current operation, but have stated their commitment to maintaining a strong security presence in Sinaloa. The next official update on the situation is expected from the Mexican Security Cabinet in the coming days.
