JUAREZ, Mexico -- The death toll in the turf war across the border continues to rise as cartels execute more people in what is supposed to be the bloodiest weekend in Juarez history.

In just the last 12 hours, 12 people have been brutally executed in El Paso's sister city. Meanwhile, officials protecting the border and first responders are on high alert.

The streets of Juarez were empty Saturday after e-mail and text messages warning of shootings in malls, restaurants and nightclubs.

A father, son, and friend of the family were killed while at a family gathering Friday night.

The violence continued Saturday morning when another man was found dead. He had more than 100 bullet holes in his SUV.

Later Saturday evening two more men were found dead in the Rio Bravo neighborhood in Juarez.

Those protecting our borders tell KFOX while the violence in Juarez is tragic, it is contained.

"It is not spilling over, but we realize the fact that bullets don't know boundaries. We do have communication with government. It is business as usual. Our agents are always vigilant. Right now the level of violence does concern us across the border and it keeps everyone on their toes," said Ramiro Cordero, a spokesman for CBP Border Patrol El Paso Sector.

First responders in El Paso were also on heightened alert Saturday morning. EMS was advised to report any torture related injuries.

KFOX called officials from Thomson Hospital, and they said they aren't taking any special measures in anticipation of more deaths, but are ready for any type of emergency.

Across the border, Juarez nightclubs were closed Friday night and officials expect the same Saturday.
