Protesters gathered across Mexico to demand justice following a grisly discovery of charred bones, shoes and clothing at a suspected drug cartel training ground.

Following the discovery of an alleged Mexican cartel "extermination site" in the western state of Jalisco, groups searching for missing relatives and activists called for a vigil and a day of national mourning in Mexico City's central Zócalo Square on Saturday in memory of the victims.

What is believed to be an abandoned ranch used by a Mexican cartel in the western state of Jalisco, is being called an "extermination" site by those who found it.
