Hitmen from one of Mexico’s most notorious drug cartels have announced a “purge” in a chilling video which has emerged online.

Members of the Jalisco New Generation Cartel (CJNG) – considered to be the country’s most dangerous drug trafficking organisation – wear creepy Halloween masks and military-style uniforms in the bizarre footage. They’re also armed to the teeth, pointing high-calibre weapons to the sky as they face the camera.

In the video shared on X, formerly known as Twitter, one hitman addresses residents of Teotihuacán, a city in the State of Mexico, and people in the surrounding areas. He announces the CJNG has “arrived” there before listing off all the towns they will be visiting on their “purge”.

He says: “This message goes out to the residents within the valleys of Teotihuacán and all of its surroundings. We’ve arrived you sons of b******. We will be moving throughout the towns of San Juan Teotihuacán, Otumba, Axapusco, Nopaltepec, Acolman, Maquixco, Atlatongo, Joquicingo, San Martín de las Pirámides, Santanas, San Luis, San Miguel, Ixtlahuaca, Tecámac, Zumpango, 5 de Mayo, San Pedro, Santa Maria, Purificación, San Sebastián Xolalpa, Belém, Oxtotipac, Tepetlaoxtoc, San Marcos, Nepantla, San Antonio, Teopancala, Coacalco.

“We’ve arrived to purge these areas you sons of b******. We are the absolute mob of Mr Mencho.” The hitmen are then heard shouting that final sentence again in unison.

The CJNG is headed by Nemesio Ruben Oseguera Cervantes, more commonly referred to by his alias El Mencho. The gang’s propensity for extreme violence has landed El Mencho at the top of both America and Mexico’s most wanted lists, with US authorities offering $10million (£8.2m) for information leading to his capture, Daily Star reports.

Miguel Ángel Félix Gallardo, often referred to as “El Padrino” (The Godfather), is considered one of the key figures in the birth of Mexican drug cartels. He founded the Guadalajara Cartel in the early 1980s, and this cartel played a significant role in the growth of the illegal drug trade in Mexico and its connections to drug trafficking across the Mexico-U.S. border.
