Moment Mexican Cartel Members Line Up 20 Gang Members Before Executing Them And Abandoning The Bodies Outside The City's Mayor Office

A cartel released disturbing video footage of the moment 20 of its rivals were lined up side-by-side before they were executed in southwestern Mexico.

Los Tlacos henchmen accused members of the rival La Bandera of 'extorting and killing innocent people' before forcing them to kneel and interrogating them at gunpoint in the middle of a forest in the state of Guerrero. 

La Bandera gang is reportedly an armed wing of Guerreros Unidos, the cartel connected to the 2014 kidnapping of 43 students in Ayotzinapa.

At least four of the victims' bodies were found dumped in the trunk of a car that was left abandoned in front of the campaign office of Iguala mayor David Gama Pérez on Wednesday morning.
