Mexico’s plague of drug-gang related violence showed no sign of let-up on Christmas Day – in the western state of Michoacan six severed human heads were found.

According to authorities, they were discovered in Jiquilpan, a municipality near the state of Jalisco – a region that has become a battleground for competing drug gangs in recent years.

The six men are yet to be identified and their bodies have not been found.

Though a particularly grim discovery, authorities regularly find dismembered body parts across Mexico’s more violent states, as cartels bury their victims in hidden graves.
