Eight members of the United States Army irregularly entered Mexican territory in the city of Nogales, Sonora, on March 25, 2026, to carry out reinforcement work on the international border fence.

The US military personnel reinforced the train’s access gate located on the border strip with barbed wire, an activity they continued working on for approximately one hour inside Mexican soil.

According to eyewitnesses, officers of the Mexican National Guard (GN) approached the U.S. military personnel and argued with them, demanding they return to their country. Far from complying, the U.S. military personnel called in additional troops carrying high-powered weapons and remained within Mexican territory.

A Mexican citizen also approached the U.S. soldiers to confront them, demanding they withdraw and stating that their presence constituted an invasion of Mexican territory. The soldiers ignored him.

During the incident, personnel from the Secretariat of National Defense (SEDENA) were present at the scene, some of them dressed in civilian clothes, and they simply observed and took photographs of what was happening.

The incident concluded at approximately 1:30 p.m. that same day, when the U.S. military personnel finished their work and quietly withdrew to their country without any further consequences being reported.
