At least 15 people were killed Friday during a clash between police and alleged drug traffickers in north Mexico, local radio reported.
The clash erupted in Ciudad Victoria, capital of Tamaulipas state, during a raid to arrest Hugo Cesar Delgado, one of the most wanted alleged drug traffickers by the U.S. Federal Bureau of Investigation (FBI), the Mexico City radio network reported.
Delgado was reportedly arrested near Rio Bravo, north of Tampico, an area close to the border with the United States, said the report.
Police said some 20 tons of cocaine were seized in the operation.
Mexican President Felipe Calderon has ordered police-military joint action against drug trafficking and organized crime throughout Mexico since he was elected on Oct. 1, 2006.
