Federal agents seize 210 firearms from tractor-trailers at Texas-Mexico border
Federal authorities intercepted two tractor-trailers carrying 210 firearms just south of the U.S.-Mexico border early Monday, detaining three suspects in what officials described as a major disruption of weapons trafficking to Mexican criminal organizations.
Security Minister Omar García Harfuch announced the seizure on social media, stating that agents stopped the vehicles on the Nuevo Laredo-Monterrey highway near Sabinas Hidalgo, Nuevo León, approximately 137 kilometers south of Laredo, Texas. The operation involved coordination between the Federal Attorney General's Office, its Criminal Investigation Agency, the Defense Ministry, the Navy, the Security Ministry and the National Guard.
The confiscated arsenal included 195 long guns, 15 short guns and an undisclosed quantity of magazines. Authorities characterized the weapons as high-powered firearms destined for criminal groups operating in Mexico.
"This action was the result of intelligence and investigative efforts to identify and dismantle the routes used to illegally introduce weapons into our country," García Harfuch said in his statement.
The seizure comes amid intensified enforcement efforts under President Claudia Sheinbaum's administration. Since she took office on Oct. 1, 2024, federal authorities have confiscated more than 30,000 firearms. During the administration's first year, Mexico seized 17,283 firearms, double the annual average of 8,564 firearms seized during the previous López Obrador administration.
The scale of gun trafficking between the two countries remains substantial despite increased interdiction efforts. Research estimates that approximately 135,000 to 500,000 firearms are trafficked from the United States to Mexico annually. Between 70% and 90% of firearms recovered in Mexico and traced by authorities originated from the United States, according to Bureau of Alcohol, Tobacco, Firearms and Explosives data.
Geographic patterns of trafficking
The location of Monday's seizure reflects broader patterns in cross-border weapons smuggling. Texas and Arizona account for the majority of crime guns traced from the United States to Mexico. Between 2017 and 2021, five states — Texas, Arizona, California, New Mexico and Florida — accounted for 79% of all traced crime guns recovered in Mexico.
The concentration of trafficking through these corridors has prompted specialized enforcement responses. The ATF established nine Firearms Trafficking Task Forces on the southwest border as part of Operation Southbound, with seven in Texas and two in Arizona, specifically targeting gun trafficking to Mexico.
U.S. interdiction efforts have also intensified in recent years. Customs and Border Protection reported intercepting 1,171 guns before they crossed into Mexico in 2023, nearly seven times the 173 guns intercepted in 2019, though this still represents a small fraction of estimated total trafficking.
Diplomatic pressure and legal setbacks
Mexican officials have recently escalated calls for the United States to address the flow of weapons across the shared border.
"Shared responsibility demands curbing drug trafficking to the United States, but also stopping, with equal firmness, the flow of weapons from the United States to Mexico," García Harfuch said.
The contrast in gun regulations between the two countries contributes to the trafficking problem. Mexico maintains strict gun control laws and operates only one legal firearms store in the entire country, located on a military base in Mexico City. Meanwhile, there were over 75,000 federally licensed firearms dealers in the United States in 2024, including independent stores, chain stores, pawnbrokers and manufacturers.
Mexico's efforts to pursue legal remedies against U.S. gun manufacturers suffered a setback in June 2025, when the U.S. Supreme Court unanimously rejected the Mexican government's $10 billion lawsuit. The court ruled that federal law shields gun companies from liability for crimes committed with their products.
Earlier this month, U.S. officials reported that a government task force had broken up an arms-trafficking ring responsible for sending military-grade firearms across the border to Mexico. The enforcement action came just days before U.S. military forces used a high-energy laser system to shoot down three drones near the Mexico border that authorities linked to Mexican cartels.
U.S. Maj. Gen. Curtis Taylor, commander of Joint Task Force-Southern Border, acknowledged the importance of bilateral cooperation in addressing border security threats.
"We greatly appreciate the support of our Mexican Army partners as we work together to combat this threat to the border region," he said.
Econometric research has documented the public safety consequences of weapons trafficking, with analysis showing a correlation between increased gun flows and homicide rates in Mexico. The findings underscore the human cost of the trafficking networks that Monday's seizure sought to disrupt.
