In Mexico, the Jalisco New Generation Cartel (CJNG) has launched terrifying reprisals for the death of its leader, Nemesio Oseguera Cervantes. Better known as “El Mencho”, he ran one of the biggest and most violent organised crime gangs in Mexico.

Since his death there have been large-scale coordinated attacks in Jalisco state, the cartel’s heartland – including at the Pacific resort of Puerto Vallarta, and the World Cup host city of Guadalajara. The Foreign Office has issued multiple warnings to British travellers in Mexico.
