A video of the Mexican cartel members lining up rivals for mass execution has been doing rounds on social media. The video, a two-minute clip, shows twenty men on their knees as the apparent executor taunts them . 

The video was posted on social media by Mexican drug members of Los Tlacos, as per New York Post reports. The 20 doomed men have been reported as a part of the Guerreros Unidos cartel, according to El País, Spanish-language daily newspaper in Spain.

A man narrating the disturbing footage says, “This plaza already has an owner,” El País reported.

“People from Iguala, here are all those who extorted money and who were killing innocent people and women. The garbage that terrorised this beautiful city,” the man says.

“In Mexico, criminals exhibit their victims, other alleged criminals, and even record their executions,” reporter Repor Torres said on Twitter.

The narrator accuses the incoming mayor of Iguala of having connections to Guerreros Unidos. The cartel is believed to be tied to the 2014 kidnapping of Ayotzinapa Rural Normal School, El País said.

Hours before the video, gang members left four bodies in front of Mayor-Elect David Gama’s home, the report added.

Iguala has long been plagued by drug gang violence. In 2014, police working for one of the gangs kidnapped 43 students from a local teachers’ college and turned them over to the gang, which apparently killed them.

On Friday, four people were reported dead in Iguala in connection to gang violence. The state prosecutors said that the victims were linked to a local criminal gang known as “The Flag.” One of the dead men was wanted for the murder of two other men.

Local media reported the car was left near what had once been the campaign headquarters of the city’s incoming mayor, but authorities did not confirm that.

On Thursday, prosecutors also said that the most famous disco in Guerrero state’s biggest resort, Acapulco, had been damaged by fire.

Local media said unidentified men intentionally set the fire, but authorities said they were still waiting for lawyers for the Baby O disco to turn over surveillance camera recordings so they could investigate the blaze.
