US Restricts Government Travel to Mexican Border City of Nogales After Security Warning

US government employees in Nogales, Mexico, have been told to limit travel and official activity to essential movement during daylight hours after the United States received information about an unspecified threat.

The US Embassy and consulates in Mexico issued the warning on Saturday. The US Consulate General in Nogales said, “Due to threat information, U.S. government activities in, and travel to, Nogales have been restricted to essential movement during daylight hours only.” It added that the alert reflected a change in the government’s security posture.

The consulate did not identify the threat or explain what information prompted the restrictions. Mexican authorities said they contacted US consular officials after the alert was issued. Sonora’s State Security Board said it had received no information pointing to a specific threat or an immediate danger to the public, but said preventive operations would continue in Nogales.

We are alerting U.S. citizens of this threat and change in posture.

The warning comes as the US State Department already lists Sonora as a Level 3 destination, advising Americans to reconsider travel. US citizens in Nogales were urged to monitor local news, remain alert and follow instructions from Mexican authorities. The guidance also tells them to seek shelter if an incident occurs and notify family or friends that they are safe.

Republican US Representative Andy Biggs of Arizona also urged Americans in and around Nogales to follow the government’s guidance. “We are praying for the safety of US citizens and personnel who may be in harm’s way,” Biggs said in a post on X. The nature of the threat behind the latest restrictions remains undisclosed.
