Mexico's government has stated that two US federal agents who died in a car crash linked to an anti-narcotics raid in Chihuahua were not authorized to operate on Mexican territory, despite reports identifying them as CIA officers. One individual entered Mexico as a visitor and the other with a diplomatic passport, neither possessing formal accreditation for operational activities. Mexican President Claudia Sheinbaum announced an investigation into potential violations of the national security law, which requires federal authorization for foreign agents. The incident, which also claimed the lives of two Mexican officials, has intensified scrutiny over the extent of US operational involvement in Mexico and underscores President Sheinbaum's stance on national sovereignty amid US demands for stricter anti-drug trafficking measures.
