Six severed heads have been found on a road in central Mexico, sparking a major investigation.
The discovery was made by local authorities early on Tuesday morning in an area that is usually peaceful and not associated with cartel violence.
The route where the severed heads were found links the central states of Puebla and Tlaxcala. Police have not yet provided a motive behind the killings, nor have they revealed any information regarding which criminal groups operating in Mexico could have been behind the horrific act.
