Street battles have erupted after the military killed a powerful kingpin known as El Mencho Battles between cartels and security officials have broken out in multiple cities across Mexico after a top drug kingpin was killed by the military. On Sunday, Mexico’s Secretariat of National Defense announced that its special forces killed Nemesio Oseguera Cervantes, also known as El Mencho, the head of the Jalisco New Generation Cartel (CJNG). Cervantes died from his wounds as a result of a military operation to capture in Tapalpa. The cartel responded by blocking roads and attacking patrol vehicles. Jalisco Governor Pablo Lemus Navarro declared a state of emergency. The violence has quickly spread to the states of Michoacan, Tamaulipas, Zacatecas, Colima, and Oaxaca.
