Mexican Cartel Leader “El Mencho” Killed in Jalisco Military Operation
Mexican drug lord Nemesio Ruben Oseguera Cervantes, widely known as “El Mencho,” was killed Sunday during a military operation in the western state of Jalisco, Mexican officials announced.
Mexico’s defense ministry said a shootout in Tapalpa left Oseguera seriously injured. He later died while being transported by air to Mexico City. Six additional cartel members were killed, and two were arrested during the operation. Members of the Mexican military were reported injured.
Authorities said several weapons and armored vehicles were seized, including rocket launchers capable of targeting aircraft and armored units. Officials added that U.S. authorities provided supporting intelligence as part of bilateral cooperation.
Leader of Powerful Cartel
Oseguera, a former police officer, led the Jalisco New Generation Cartel, often referred to as CJNG. The cartel, based in Jalisco, home to the major city of Guadalajara grew rapidly into one of the most powerful criminal organizations in Mexico.
The group rivaled the Sinaloa Cartel, formerly led by imprisoned drug kingpin Joaquin Guzman, also known as “El Chapo,” who is serving a life sentence in the United States.
Mexican officials described Oseguera’s death as a significant development in the country’s long-running fight against drug trafficking organizations accused of smuggling cocaine and fentanyl into the U.S.
Violence and Travel Disruptions
Following the announcement, unrest broke out across several states. Reports indicated vehicles were set on fire and highways were blocked by armed individuals. Mexico’s security cabinet reported 21 active highway blockades in Jalisco alone as of Sunday afternoon, along with damage to multiple government bank branches.
Flights to Puerto Vallarta and Guadalajara experienced cancellations and diversions. Major airlines, including Delta Air Lines, American Airlines, and Alaska Airlines, were affected.
Sporting events were also postponed, including Liga MX matches and a Liga MX Femenil game between Chivas and Club América.
Mexican President Claudia Sheinbaum said authorities were coordinating across states to restore order, adding that the government works daily for “peace, security, justice, and the well-being of Mexico.”
Jalisco Governor Pablo Lemus Navarro urged residents to remain at home until the situation stabilizes. The U.S. Embassy advised American citizens in affected areas to shelter in place.
U.S. Intelligence Support
Mexico’s defense ministry confirmed that U.S. officials provided complementary intelligence information for the operation.
U.S. Deputy Secretary of State Christopher Landau described the killing as a significant development but expressed concern about the violence that followed.
