American troops installed signs on a beach in northeast Mexico declaring the area "restricted" by the U.S. Department of Defense, it has been reported.

Video on social media appears to show Mexican marines removing the signs purportedly at Playa Bagdad, near where the Rio Grande river flows into the Gulf of Mexico.

The signs warned that unauthorized access or photography was not permitted, and that "if you are found here, you may be detained and searched."

The U.S. Embassy in Mexico shared a comment from the Pentagon confirming that contractors had put up signs to mark the "National Defense Area III," and that "changes in water depth and topography altered the perception of the international boundary's location."

Mexico’s Ministry of Foreign Affairs said its navy had removed the signs because they were on Mexican territory, according to reports.

Meanwhile, Mexico’s President Claudia Sheinbaum - who has been engaged in a war of words with President Donald Trump over U.S. strikes on alleged drug cartels - said the International Boundary and Water Commission (IBWC) would resolve the dispute.

Newsweek contacted the Pentagon for comment by email outside of regular working hours.
