Security concerns have emerged in Nogales, Sonora, involving both local criminal activity and international diplomatic responses. On August 25, a 19-year-old man was arrested in the 5 de Mayo neighborhood for allegedly engaging in ‘halconeo’, the practice of monitoring and reporting police movements via radio transmitter.

Following reports of potential threats in the region, the U.S. Consulate General in Nogales issued a security alert, restricting U.S. government activities and travel to essential movements during daylight hours. While the U.S. Department of State maintains a Level 3 travel advisory for Sonora, advising citizens to ‘reconsider travel’ due to violence, the Sonora State Security Board stated they have no data confirming a specific threat to the general population.

As of September 8, the U.S. government continues to restrict official activities and personnel travel to essential daylight movements via TravelGov, citing information regarding threats without specifying a particular group or incident. Local authorities, including Mayor Juan Francisco Gim, stated they are maintaining close communication with the U.S. Consulate, though they have not received specific details regarding the nature of the threat. In response to the alert, the Sonora Security Board recently met with the 45th Military Zone to strengthen local security plans and reinforce operations.
