Shocking Scenes at U.S.-Mexico Border

The border city between Mexico and the United States known as Juarez has become one of the most violent regions in Mexico. Last year, foreigners wishing to visit the border area were warned by the State Department not to go. Currently, most of the violence is attributed to the overwhelming influence of rival Mexican drug cartels, which battle for control of the lucrative drug routes into the United States.

Here, in the shadow of an ambulance, a gun casing is the only evidence of a recent drug-related shooting.
