Hitmen from the Viagras cartel have shared footage of a rival confessing his “sins” before taking a butcher’s knife to his neck.
Beheadings are becoming the cartels’ “signature move” as they adopt the sick video tactics from terror group ISIS.
In the jihadi inspired clip, a young man sits bound as he talks directly into the camera.
He is believed to be a soldier from a rival, and included are pictures of him armed with an AK-47 in the jungle.
Following his confession, the thugs then bend his neck backwards and viciously behead him.
“The beheading technique is quite similar to ISIS”
Viagras posted the video on social media with a direct warning to the Jalisco New Generation Cartel (JNGC).
Drug gangs are both at war with each other and law enforcement agencies from Mexico and the US.
Cartels attempt to smuggle cannabis, cocaine, heroin, and meth across the border from the South American country into the southern states of America.
Earlier this year, a location scout for Netflix drama Narcos was killed in a suspected cartel attack in Mexico.
Organised crime expert Gustavo Fondevila said: “The beheading technique is quite similar to ISIS and has a long tradition in military combat as a strategy to terrorize the enemy.”
Separate incidents were also recorded in the city of Guadalajara nearby, where two severed heads were found with notes directed at the JNGC.
Dozens of beheadings have been recorded this year, with 2017 believed to be bloodiest year in Mexico’s long-running drug war, reports the Daily Beast.
In the newly released clip, the victim claims to be the brother of notorious CJNG cartel boss El Duende – real name Juan Carlos Márquez Pérez – who was arrested in 2015
“This execution video is definitely out of character for the Viagras and appears to be an escalation in their use of violence against the CJNG cartel,” said security expert Robert Bunker.
He said: “A safe guess would be that their fight with CJNG may not be going well and they see the need to ‘ramp up the terror’ against that group in order to better protect their territories and illicit interests.”
Extreme violence has characterised the war on drugs in Mexico, with gang members using increasingly vicious tactics.
Police and soldiers are working on the frontline to try and curb the cartels as murder rates skyrocket.
Previously, retired Drug Enforcement Administration officer Mike Vigil warned Mexican cartels make ISIS look like “choir boys”.
