El Mencho killed in U.S.-assisted operation as cartel violence erupts

Mexican security forces killed Nemesio Rubén Oseguera Cervantes, known as El Mencho, after information from U.S. authorities assisted the operation. The CJNG leader’s death followed clashes that sparked violence across several states, prompted flight disruptions and shelter-in-place advisories for travelers, and left four cartel members dead with two detained as weapons and armored vehicles were seized. U.S. officials described the operation as a significant cooperative effort between the two countries and praised the development.
