Spring breakers warned against Mexico travel

The bureau's Los Angeles field division said Monday that it discourages travel to Tijuana and Rosarito Beach, noting that both cities just south of San Diego have witnessed a lot of drug-fueled violence. Rosarito has long been a mecca for Southern California students on spring break.

The warning goes a step further than one issued by the State Department last month advising travelers to Mexico to avoid areas of prostitution and drug-dealing and to take other commonsense precautions.

The ATF is responsible for preventing arms smuggling into Mexico.
