Mexican army kills leader of powerful Jalisco New Generation Cartel during operation to capture him

Mexican forces killed Nemesio “El Mencho” Oseguera Cervantes, leader of the Jalisco New Generation Cartel, sparking violence and roadblocks across Jalisco.

MEXICO CITY — The Mexican army killed the leader of the Jalisco New Generation Cartel, Nemesio Rubén Oseguera Cervantes, "El Mencho, " on Sunday, decapitating what had become Mexico's most powerful cartel and giving the government its biggest prize yet to show the Trump administration its efforts.

Oseguera Cervantes was wounded in an operation to capture him Sunday in Tapalpa, Jalisco about a two-hour drive southwest of Guadalajara and he died while being flown to Mexico City, the Defense Department said in a statement. The state is the base of the cartel known for trafficking huge quantities of fentanyl and other drugs to the United States.

During the operation, troops came under fire and killed four people at the location. Three more people, including Oseguera Cervantes, were wounded and later died, the statement said. Two others were arrested and armored vehicles, rocket launchers and other arms were seized. Three members of the armed forces were wounded and receiving medical treatment.

The killing of the powerful drug lord set off several hours of roadblocks with burning vehicles in Jalisco and other states. Such tactics are commonly used by the cartels to block military operations. Jalisco canceled school in the state for Monday.

Videos circulating on social media showed plumes of smoke billowing over the tourist city of Puerto Vallarta in Jalisco, and people sprinting through the airport of the state's capital in panic. On Sunday afternoon, Air Canada announced it was suspending flights to Puerto Vallarta "due to an ongoing security situation" and advised customers not to go to their airport.
