(Washington, DC) -- The State Department is warning Americans headed to border towns in Mexico to use extreme caution following drive-by shootings that killed three people over the weekend, including two Americans. The "Los Angeles Times" reports two separate shootings took place in broad daylight near the U.S. Consulate in the Mexican border city of Juarez. The State Department is allowing Americans staffing consulates in five border towns to evacuate their families. In Saturdays attacks, an American employee working at the Juarez consulate was killed along with his American wife, but their infant child survived the shooting. The third victim in a separate shooting was the Mexican husband of a Mexican national who is employed by the consulate. Two of their children were wounded in the gunfire, which is being blamed on drug cartels.
