Police in Mexico say they have found four bodies hung from a bridge in an affluent town south of Mexico City.
The four men had been decapitated and mutilated before being hung by their ankles from the bridge outside Cuernavaca, in the state of Morelos.
A message had been left with their heads warning that anyone supporting Edgar Valdez would risk a similar fate.
Edgar Valdez is reportedly fighting Hector Beltran Leyva for control of the influential Beltran Leyva drug cartel.
Cuernavaca, a city of 350,000 and a popular weekend retreat spot for wealthy residents of Mexico City, is at the centre of the turf war.
The cartel has been without a leader since Arturo Beltran Leyva was killed by the security forces in December. BBC News
