(CNN) -- Three Americans died in weekend violence in the area of Ciudad Juarez, Mexico, a U.S. official said.
"Two citizens were fatally shot early Sunday close to the Zaragoza international bridge," State Department spokesman Philip Crowley said Monday. "In a separate incident, another U.S. citizen was fatally wounded in Ciudad Juarez itself."
Violence is rife in the area, as the Juarez and Sinaloa cartels battle for control of lucrative smuggling routes into the United States, where demand for illegal drugs is strong.
