Mexican President Claudia Sheinbaum on Tuesday ruled out allowing U.S. strikes against cartels on Mexican soil, a day after President Trump said he was willing to do whatever it takes to stop drugs entering the U.S. Meanwhile, Mexican and American diplomats were trying to sort out what may have been an actual U.S. incursion.
On Monday, men arrived in a boat at a beach in northeast Mexico and installed some signs signaling land that the U.S. Department of Defense considered restricted.
Mexico's Foreign Affairs Ministry said late Monday that the country's navy had removed the signs, which appeared to be on Mexican territory. "The origin of the signs and their placement on national territory were unclear," the ministry said in a statement.

The signs read in English and Spanish, "Warning: Restricted Area," and went on to explain that it was Department of Defense property and had been declared restricted by "the commander." It said there could be no unauthorized access, photography or drawings of the area.
CBS 4 News Rio Grande Valley posted an image of one of the signs on social media.
The U.S. Embassy in Mexico shared a comment from the Pentagon Tuesday about the incident, confirming that contractors putting up signs to mark the "National Defense Area III" had placed signs at the mouth of the Rio Grande.
"Changes in water depth and topography altered the perception of the international boundary's location," the statement said. "Government of Mexico personnel removed 6 signs based on their perception of the international boundary's location."
The Pentagon said the contractors would "coordinate with appropriate agencies to avoid confusion in the future."
Mexico had contacted its consulate in Brownsville, Texas, and then the U.S. Embassy in Mexico City. Eventually, it was determined that contractors working for some U.S. government entity had placed the signs, Sheinbaum said.
