The US ambassador to Mexico, Ronald Johnson, said US Coast Guardsmen came under fire in a border area.

President Claudia Sheinbaum said Mexico asked the United States for all the evidence because it has none. Some 500 US troops, along with helicopters, drones and anti-drone equipment, have been sent to the border since the alleged shooting. The Washington Post reported that the two countries deployed hundreds of troops to a border area where US officials said members of the US Coast Guard came under fire.
