Mexico: No Evidence of Border Gunfire, Asks U.S. for Proof

Mexico City — Mexican President Claudia Sheinbaum said on Monday that her government has requested evidence from U.S. authorities regarding allegations that gunfire originated from the Mexican side of the border and targeted U.S. personnel. She said Mexican security forces had not detected any such incident.

"We asked for all the evidence because we have no evidence," Sheinbaum said during her daily press conference. She added that no personnel from Mexico's National Guard, Army, or Navy had detected shots fired from Mexican territory toward the United States.

Her comments came a day after U.S. Ambassador Ronald Johnson said on X that "shots were fired at U.S. Coast Guard personnel" in a border area where the Mexican state of Tamaulipas meets Texas, and where Mexico on Sunday announced the deployment of Army and National Guard troops.

Johnson's remarks followed Mexico's announcement late Sunday of a joint border security effort known as "Operation Mirror," under which 500 troops, helicopters, drones, and anti-drone equipment will be deployed along the frontier.

The incident comes as Mexico and the United States deepen security cooperation, though Sheinbaum has repeatedly rejected any U.S. military intervention in Mexico.

Sheinbaum said Mexican authorities proposed "mirror operations" with U.S. agencies after being informed of the alleged incident, as a precautionary measure.

"To avoid any of these situations, what was proposed was that mirror operations be carried out so there would be no problems," she said. "We have not been given any evidence that these shots actually occurred, but to prevent any situation a mirror operation has already been carried out."
