U.S. officials said Coast Guard personnel came under gunfire from the Mexican side of the border near Garceno, Texas, in Starr County on Sept. 26 while intercepting migrants on the Rio Grande, and that Coast Guard personnel returned fire. Officials said no injuries or equipment damage occurred, and it remains unclear who fired first. Following the incident, hundreds of U.S. troops were repositioned to the Rio Grande Valley, and Mexico said it was deploying additional forces to its side of the border, with reported figures ranging from roughly 160 to 500 troops. Mexican President Claudia Sheinbaum said Mexico’s military had detected no shots fired from Mexican territory and asked the United States to provide evidence of the incident.
