MEXICO CITY, May 6 (Xinhua) -- Mexican President Claudia Sheinbaum on Wednesday reaffirmed that national sovereignty cannot be negotiated and that state governments cannot authorize foreign security operations.
Sheinbaum made the remarks in response to a case in the northern state of Chihuahua, where unauthorized U.S. CIA agents participated in an anti-drug operation last month and died in a road accident. Mexico's attorney general is investigating under what authority the agents were operating and who gave the instructions.
"This is about interference -- the presence of foreign agents in security operations," she said.
The incident coincides with a U.S. extradition request for Ruben Rocha, Sinaloa's governor on leave, accused of drug and arms trafficking. ■
