White House Press Secretary says "ättacks on U.S. citizens are unacceptable," following the kidnapping of four Americans in Mexico. This comes after a road trip to Mexico for cosmetic surgery ended with two Americans dead, and two others found alive in a rural area near the Gulf coast, after a violent shootout and abduction that was captured on video, officials said Tuesday. The surviving Americans were back on U.S. soil after being sped to the border near Brownsville, the southernmost tip of Texas, in a convoy of ambulances and SUVs escorted by Mexican military Humvees and National Guard trucks with mounted machine guns. The U.S. citizens were found in a rural area east of Matamoros called Ejido Tecolote on the way to the Gulf coast known as “Bagdad Beach,” according to Mexican authorities.
