Seven men were gunned down at ahome in Ciudad Juárez, México Saturday night capping another bloody weekend in the border city leaving 20 people dead.

At least 20 people were killed in drug-gang violence over the weekend in this northern Mexican border city, including seven found dead outside one house.

The seven men were believed to have been at a family party when they were gunned down, said Arturo Sandoval, a spokesman for the attorney general's office in Chihuahua state, where Ciudad Juárez is located. Five were found dead in a car, and the other two were shot at the entrance of the home.

There have been several such massacres in Ciudad Juárez, a city held hostage by a nearly three-year turf battle between the Juárez and Sinaloa cartels.

Few residents now venture out to bars and restaurants. And like those attacked on Saturday, others have discovered that they aren't even safe in their own homes: Last month, gunmen stormed two neighboring houses and massacred more than a dozen young people attending a party for a 15-year-old boy.

Ciudad Juárez, across the border from El Paso, Texas, has become one of the world's deadliest cities in the time that the two cartels have been fighting. More than 6,500 people have been killed since the start of 2008.

But the violence doesn't stop there. In the southern city of Oaxaca, police found a human head in a gift-wrapped box left Saturday night on the side of a cliff popular for its view of the picturesque colonial center.

Reporters at the scene saw a threatening message left with the head signed, "the last letter Z," an apparent reference to the Zetas drug gang.

The gruesome find came a week after two young men who had been involved in violent university protests and other conflicts were gunned down in the middle of the day in a public plaza.

An e-mail purportedly from the Zetas claimed responsibility for those slayings and said that the two were killed for falsely representing themselves as members of the gang.

Oaxaca state Attorney General Maria de la Luz Candelaria Chinas said the e-mail is suspected to be fake, although she said authorities had not ruled out the possibility that the Zetas sent it.

Mexican government officials describe the Zetas — former hit men for the Gulf cartel who became independent this year — as a sort of franchise with units across the country. But officials say some of those cells are copycats using the Zetas name to intimidate extortion and kidnap victims.

The Zetas have grown in power over the past decade, and experts warn their clout could grow following the death Friday night of one the gang's major enemies, Gulf cartel leader Antonio Ezequiel Cárdenas Guillén. The kingpin, known as "Tony Tormenta" or "Tony the Storm," was killed in a shootout with marines.

Although there have been some beheadings in recent years, cartel-style violence is rare in Oaxaca, the capital of the southern state by the same name, especially compared to northern México or the central Pacific coast.
