On Sunday, authorities in Mexico attempted to capture the notorious cartel boss known as “El Mencho”.
They tracked Nemesio Rubén Oseguera Cervantes down to a cabin in the western state of Jalisco – his stronghold – and he was fatally wounded in the raid. The firefight also killed several of his heavily-armed accomplices, including his likely successor.
He was head of the Jalisco New Generation Cartel (CJNG), known for trafficking vast quantities of fentanyl and cocaine into the US.
In 2025 it was designated a foreign terrorist organisation by Donald Trump‘s administration.

His death prompted waves of violent retaliation as the cartel put on a show of strength in areas far beyond Jalisco and into tourist hotspots.
The authorities have calmed the situation – for now – but fears are mounting that more violence will erupt as the cartel seeks to regroup after the death of its leader.
But why has the Mexican government chosen this moment to escalate its fight against the cartels?
The security situation has brought the soccer World Cup – just months away – into sharp focus with questions about the ability of the Mexican authorities to keep fans safe.
Mexico City-based journalist Oscar Lopez explains why this happening now.
