Motorists find grisly sight of decapitated heads on road linking states of Puebla and Tlaxcala in Mexico

Motorists on a well-used road in Mexico were met with a grisly scene — with six decapitated heads being lined up on the thoroughfare.

Shocked drivers on the road linking the states of Puebla and Tlaxcala in the centre of the country made the discovery, which is being blamed on a gang feud.

All the heads were men, with another severed head and body being found in the city of Colima.

A prosecutor said that extreme violence on such a level was rare in Puebla and Tlaxcala, though a gang war had been bubbling away.

Local media reported that a pamphlet was found near one of the severed heads, saying it was a settling of scores between gangs that rob fuel.

Violence such as a decapitation is more common in Mexico’s north and along the Pacific coast where drug cartels operate.

Authorities found 20 bodies — five of them headless — on a main road in the north-west state of Sinaloa in July.

The bodies of four of the victims were hung from a bridge.

The Government has deployed thousands of soldiers to Sinaloa in a bid to end the violence, which is believed to have left 3000 people dead or missing.

Mexico deployed troops to take on the powerful drug cartels in 2006.

Since then about 480,000 people have died in drug-related violence.
