Mexican Violence

The decapitated bodies of four men were hung from a bridge Sunday in this

central Mexican city besieged by fighting between two drug lords.
A gang led by kingpin Hector Beltran Leyva took responsibility for the
killings in a message left with the bodies, the attorney general's office
of Mexico state said in a statement.

The beheaded and mutilated bodies were hung by their feet early Sunday
from the bridge in Cuernavaca, a popular weekend getaway for Mexico City
residents.

Mexican authorities say the cartel split between a faction led by Hector
Beltran Leyva, brother of Arturo, and another led by Edgar Valdez
Villareal, a U.S.-born kingpin known as "the Barbie."

Guerrero state has been wracked by drug-gang violence, including the
strife within the Beltran Leyva cartel. There have also been a series of
deadly carjackings this year along highways in the state.

Mexico has seen unprecedented gang violence since President Felipe
Calderon stepped up the fight against drug trafficking when he took office
in December 2006, deploying thousands of troops and federal police to
cartel strongholds.

Since then, more than 28,000 people have been killed in violence tied to
Mexico's drug war.
