A Sept. 26 exchange of gunfire near Garceno, Texas, has prompted a dispute between the United States and Mexico over where the shots originated, despite ongoing security coordination between the countries.
The U.S. Coast Guard told Fox News Digital that personnel involved in joint interdiction operations were fired upon from the Mexican side of the border and returned fire. The service said no one was injured and no Coast Guard vessels or equipment were damaged. It said the circumstances remain under investigation.
Mexican President Claudia Sheinbaum has called for evidence that the gunfire came from Mexican territory. She told reporters that Mexico had no evidence of shots originating there and said Mexican security forces had not detected them.
A State Department spokesman said the United States had shared available information with Mexican authorities through official channels. The department did not say what information was provided or when. U.S. officials have not publicly identified the shooters or explained in detail how they determined the shots came from Mexico.
Sheinbaum said Mexico’s military ministry maintains communication with U.S. Northern Command and the Coast Guard, and that a coordinated “mirror operation” remains active. Her remarks did not make clear whether Mexico had received the information Washington says it shared.
The incident took place during broader border-security activity. The Coast Guard described expanded operations in the region, while Mexico’s Navy Ministry reported deploying personnel, vehicles and drones to the Tamaulipas sector. U.S. Northern Command separately told Fox News Digital that American troops were being repositioned to the Rio Grande Valley ahead of an anticipated seasonal rise in attempted crossings.
The account of the shooting and official statements were reported by Fox News Digital. The available information does not resolve the disagreement over the origin of the gunfire. The Coast Guard investigation is ongoing.
