Mexico probes US role in anti-cartel ops

Mexican President Claudia Sheinbaum announced on Monday that her government will investigate whether national security law was violated after U.S. officials were involved in anti-cartel operations in the northern state of Chihuahua. The statement signals a potential diplomatic friction over U.S. involvement in Mexican internal security matters. Sheinbaum's comments reflect a careful balancing act between cooperating on cross-border security and asserting national sovereignty. The probe will examine the legal boundaries of foreign involvement in domestic law enforcement efforts.
