Mexico says two US federal agents killed in crash were not authorized to operate in the country

Mexico's Ministry of Security stated that two US federal agents killed in a car crash in Chihuahua were not authorized to participate in any operations on Mexican soil. The agents, later confirmed by the AP to be CIA officers, were reportedly returning from destroying a clandestine drug lab when their vehicle drove off a ravine and exploded, also killing two Mexican officers. Mexican law prohibits foreign agents from participating in operations within its territory, and officials from both countries have offered contradictory accounts of the incident.
