“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 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.’ … 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. … The Pentagon said the contractors would ‘coordinate with appropriate agencies to avoid confusion in the future.'” (11/19/25)
