Claudia Sheinbaum said Mexican authorities had found no evidence that gunfire had been directed toward the United States from Mexican territory and requested information about the incident from the U.S. administration.
The Mexican president said at her daily press briefing that personnel from the National Guard, the Defense Ministry and the Navy had not detected gunfire from the Mexican border toward the U.S. border. The Mexican administration requested evidence from the United States to determine whether shots had been fired and how the incident had occurred.
Joint patrols follow U.S. ambassador’s statement
The request came after U.S. Ambassador to Mexico Ronald Johnson said that U.S. Coast Guard personnel operating in the border region had been targeted in an armed attack.
Following the allegations, Mexico and the United States began coordinated patrols on their respective sides of the border. Security forces from the two countries began monitoring activity along the shared border together.
