The Mexican army killed Nemesio Rubén Oseguera Cervantes, the leader of the Jalisco New Generation Cartel (CJNG), on Sunday. This has led to outbreaks of violence in parts of Mexico as the cartel reacts to the loss of its top commander.

Why it matters

The CJNG is one of the most powerful and violent drug cartels in Mexico, responsible for much of the country's ongoing cartel-related violence and crime. The death of its leader is a significant blow, but could also trigger retaliatory attacks and unrest as the cartel tries to reassert its dominance.

The details

Oseguera Cervantes, known as 'El Mencho', was killed in a military operation on Sunday. He had been one of Mexico's most wanted fugitives for years, with a $10 million reward on his head from the U.S. government. His death has led to reports of roadblocks, fires, and other acts of violence in parts of western Mexico as the CJNG reacts to the loss of its top leader.
