Omar García Harfuch, Mexico’s Secretary of Security and Citizen Protection, announced the commencement of “Operation Sable.” This joint strategy is led by the Mexican Navy (Semar) to prevent and dismantle criminal organizations in the Interoceanic Corridor of the Tehuantepec Isthmus. This region is vital for Mexico’s economic and logistical development.

Who is Omar García Harfuch?

Omar García Harfuch is a high-ranking Mexican official responsible for overseeing national security and citizen protection. His role involves coordinating efforts among various government agencies to ensure the safety and well-being of Mexican citizens.

Why is the Tehuantepec Isthmus Significant?

The Tehuantepec Isthmus is a crucial region for Mexico’s economic and logistical growth. It connects the southern and northern parts of the country, facilitating trade and transportation. The area’s strategic importance makes it a target for criminal organizations seeking to control key transportation routes.

Operation Sable Details

During a federal press conference, García Harfuch explained that “Operation Sable” is a coordinated plan involving the Navy and all security cabinet institutions. The operation includes troop deployment and intelligence actions to prevent and, if necessary, apprehend specific targets.

Preventive Nature of the Operation

García Harfuch emphasized that the intervention is preventive, based on reports and indications of possible attempts by criminal groups like “Los Cromo” to seize railway routes and the logistical corridor. He stressed that this strategy aims to anticipate potential crimes rather than merely addressing risks.

Arrests in Connection with the Murder of Four-Year-Old Girl

In the same context of security actions in the Isthmus, the Oaxaca State Attorney General’s Office (FGEO) reported the detention of three individuals allegedly involved in the disappearance and murder of four-year-old Noelia Daylen.

Details of the Case

The girl went missing on November 10 in Juchitán de Zaragoza and was later found dead in a house in the La Planta colony. Her mother, 22, and two others were gunned down on Avenida Vicente Guerrero, prompting a multi-agency search. The detained suspects were identified as R.E.B.N., M.G.S.P., and R.I.P.G., hailing from the Mexico State and Chiapas, respectively.

Ongoing Investigation

The investigation remains open, as the crimes may be linked to a criminal cell present in the region. The interagency operation involving Semar, the Secretariat of Defense, National Guard, State Police, and State Investigation Agency led to the arrests.
