A car bomb attack in Zacatecas is raising fears of a new escalation in Mexico’s cartel conflicts. Mexican authorities suspect that the Jalisco Cartel New Generation (Cartel Jalisco Nueva Generación – CJNG) was involved in the blast in Ojocaliente, Zacatecas, a strategically important drug‑trafficking corridor located between Aguascalientes and Jalisco.
The car bomb was detonated outside the police headquarters on August 30, 2026, leaving at least eleven people injured and affecting more than 63 homes and 15 cars. The explosion is the latest development in a growing territorial dispute between the Mayiza faction of the Sinaloa Cartel and the CJNG.
As violent inter‑cartel conflict makes a comeback in the state, Zacatecas’ Governor David Monreal and State Security Chief Arturo Medina have highlighted the evolving tactics of criminal groups. The use of car bombs, drones rigged with explosives, and landmines are just some of the criminal tactics and innovations affecting officials and civilians alike as the Mayiza attempts to consolidate its recent expansion in the northern and central parts of Zacatecas, where it contests territory with the CJNG. The escalating conflict has also been marked by a rise in the number of explosive attacks: from one incident in 2024 to six in 2025 and ten so far in 2026, according to Monreal.
The rising violence is an indicator that a reported “pax narca,” in which the rivals pledged to keep homicides in the state low, has been upended. The temporary truce showed signs of falling apart after a series of disappearances and attacks between July 16 and 18, 2026, which left 10 people dead across the municipalities of Pánuco, Morelos, and Sain Alto, five of whom were found hanged from bridges along the Zacatecas–Saltillo highway. Three days later, the Mayiza faction led by Ismael Zambada Sicairos, alias “Mayito Flaco,” and their allies, Los Cabrera, claimed responsibility for the killings.
The statement included a clear warning to the Zacatecas State Governor: “We ask you, Governor David Monreal, to comply with and respect the agreements that your cabinet has with our organization, since, for our part, we are complying.”
Among the victims were the former mayor of Sombrerete, several officials and entrepreneurs from the municipality of Fresnillo, and a former city council member from the neighboring state of Durango.
Not long after the attacks, on August 24, 2026, videos circulated online appearing to show the CJNG declaring war on Mayiza leader Mayito Flaco, the Cabreras, and the government officials they accuse of aiding and abetting the faction in Zacatecas.
As CJNG–Mayiza tensions continue to intensify, the bombing, which authorities suspect was carried out by CJNG in Ojocaliente, is particularly significant given the municipality’s strategic importance for control of southeastern Zacatecas, typically regarded as Mayiza territory.
At the heart of the Mayiza faction is Ismael Zambada Sicairos, better known as Mayito Flaco. To find out more about the man behind the criminal group expanding beyond its traditional strongholds, read our Mayito Flaco profile here.
