A diplomatic dispute has escalated after six U.S. Department of Defense warning signs were discovered on Playa Bagdad, a beach in northeast Mexico near the Rio Grande. Witnesses reported that several men arrived by boat and installed signs labeling the area as “Department of Defense property” and designating it as a “Restricted Area.”
The warning notices, written in both English and Spanish, cautioned that unauthorized access, photography, or drawings were forbidden and warned that individuals “may be detained and searched.”

Mexico Removes Signs and Demands Clarification
Mexico’s navy quickly removed the signs and said their origin was unknown. The Ministry of Foreign Affairs later confirmed that the markers appeared to be placed within Mexican territory and formally requested an explanation from the United States.
Because fluctuating water levels and shifting topography at the Rio Grande can blur border lines, the International Boundary and Water Commission was assigned to investigate whether a boundary misunderstanding played a role.
Pentagon Blames Contractor Mistake
According to the U.S. Embassy, the Pentagon responded by saying that private contractors were responsible for placing the signs and had mistakenly installed them while marking “National Defense Area III.”
The Pentagon explained that natural changes in water depth and terrain contributed to confusion over the border’s exact location. The Department of Defense added that it would “coordinate with the appropriate agencies” to prevent similar incidents.
The beach lies near SpaceX’s Starbase launch facility on the Texas side, an area used by both the Department of Defense and NASA. Mexican President Claudia Sheinbaum noted that Mexico has previously raised concerns about SpaceX debris falling into Mexican territory.
Sheinbaum Rejects Trump’s Comments on Mexico
The beach incident came just one day after former President Donald Trump said he would take whatever action necessary to stop drug trafficking into the U.S., even suggesting the possibility of military strikes in Mexico.
“Would I launch strikes on Mexico to stop drugs? It’s OK with me,” he said, claiming similar strategies had already worked in other areas.
President Sheinbaum strongly rejected the statement, emphasizing that Mexico welcomes intelligence cooperation but will not allow foreign military action within its borders. She said she directly informed both Trump and U.S. Secretary of State Marco Rubio that Mexico conducts operations “in our territory” and refuses any foreign government acting independently inside Mexico.
