Mexico's plague of violence continued on Christmas Day with the discovery of six decapitated heads in one state and the killing of seven people in another.
The Michoacan state prosecutor's office said the six heads were found in Jiquilpan, a municipality near the state of Jalisco in a region that has been a battleground between competing drug gangs in recent years.
It said the six men had not yet been identified and their bodies had not been found.
Meanwhile state security officials in the neighbouring state of Guerrero said gunmen entered a house and shot dead seven people in the municipality of Atoyac de Alvarez.
Five were members of one family and two were a married couple.
State security spokesman Roberto Alvarez Heredia said two of the seven killed were municipal police officers and one a state police officer.
The preliminary investigation suggested the gunmen wanted to kill one of the victims in a revenge attack but ended up killing them all.
Guerrero, where Acapulco is located, is one of the states most plagued by drug gang violence.
