Drug cartels in Mexico are increasingly utilizing car bombs, explosives-laden drones, and improvised explosive devices, a tactical shift that risks deepening friction with the administration of U.S. President Donald Trump. The most recent escalation occurred on a Sunday night outside a police station in Ojocaliente, a city located 360 miles northwest of Mexico City. According to statements made by Mexico’s security chief Omar García Harfuch during a joint visit to Zacatecas with President Claudia Sheinbaum, the blast involved 200 kilograms of explosives. While no fatalities were reported, the explosion injured 11 people and damaged more than 60 homes in the city center. State Attorney General Cristian Paul Camacho reported that Zacatecas has logged 23 explosive attacks this year alone. That tally includes six incidents involving motorcycles or cars packed with explosives.
### Evolution of Cartel Explosives
The deployment of heavy explosives by criminal syndicates represents a departure from traditional firearm conflicts. Academic researchers and security analysts note that the systematic integration of explosive technology began roughly five years ago. Initially, cartels utilized drones to drop payloads on rival factions and security forces, alongside burying explosive devices in the ground to secure territory. By 2023, roadway bombs planted in the western state of Jalisco killed six individuals and left 14 others wounded. The mounting threat prompted the Mexican military to disclose its first nationwide seizure figures that year, revealing that approximately 2,800 explosive devices had been intercepted over the preceding four and a half years. The tempo of seizures and attacks accelerated into subsequent years. Authorities deactivated nearly 3,200 devices in Michoacán state alone in the following year. In 2025, an explosive device in Michoacán killed eight soldiers, marking one of the deadliest such incidents in Mexico. Vanda Felbab-Brown, an organized crime expert at the Brookings Institution, described the trend as a severe deterioration in security conditions. She noted that the expanded use of high-grade ordnance significantly raises the baseline of fear and retaliation across affected regions.
### Historical Context and Strategic Motives
While car bombings remain infrequent in Mexico compared to historical conflicts in nations like Colombia, they have appeared periodically over the last three decades. University of Coahuila professor Victor Manuel Sánchez, who has tracked the phenomenon over decades, pointed to a 1994 attack in Guadalajara orchestrated by the Tijuana Cartel against Ismael “El Mayo” Zambada, a co-founder of the Sinaloa Cartel who was later convicted in the United States. In recent years, attribution for urban car bombings has frequently pointed toward the CJNG. Security officials linked the group to a December vehicle bombing in Michoacán that left five dead, as well as the recent police station attack in Zacatecas. The CJNG is among the Mexican criminal organizations designated as foreign terrorist organizations by the Trump administration, which has repeatedly threatened military action against the cartels. Carlos Pérez Ricart, an international studies professor at Mexico’s CIDE university, explained that cartels deploy car bombs primarily to coerce authorities, intimidate adversaries, and project power when criminal networks feel under siege.
### The Terrorism Label and Political Stakes
The Mexican government has consistently rejected labeling cartel violence as terrorism. Experts note this resistance stems from fears that a terrorism designation could serve as a legal pretext for foreign intervention, while simultaneously damaging vital tourism and investment sectors. Official arguments frequently emphasize that cartels operate with profit motives rather than political or ideological agendas. Despite this administrative stance, civilian populations have repeatedly borne the brunt of explosive attacks. In 2008, grenades were hurled into crowds celebrating Independence Day in Morelia, the capital of Michoacán, killing eight people and wounding dozens. President Sheinbaum defended current federal security initiatives during her appearance in Zacatecas, asserting that a nationwide reduction in killings demonstrates that the government’s enforcement strategy is yielding results.
