On Monday, June 22, 2026, US border officials in Tucson, Arizona, intercepted 43,000 rounds of ammunition destined for Mexico, highlighting ongoing efforts to curb illegal arms trafficking. The seizure took place at the Mariposa port of entry, where two vehicles were found carrying the large cache of bullets.

According to US Ambassador Ronald Johnson, who shared the news on social media, one vehicle contained 40 boxes with 15,000 cartridges, while the other held 44 boxes with 28,000 rounds of 7.62×39 caliber ammunition—commonly used in assault rifles such as the AK-47.

Johnson emphasized that this operation reflects the commitment of the US government to disrupt the flow of illegal weapons and disarm criminal cartels. He also praised the role of advanced non-intrusive inspection technology in detecting illicit activities at the border.

“Regardless of the methods criminals use to smuggle arms and ammunition, US officers will detect them,” Johnson stated. He added that cooperation between the United States and Mexico strengthens security and makes both nations safer.

This incident underscores the complex challenges faced by border regions and the importance of coordinated efforts to address violence and illegal trafficking. For communities on both sides, investments in infrastructure and technology—like the upcoming cable car system in Puebla—offer promising alternatives to improve safety and connectivity, fostering inclusive development and social progress.
