SAN DIEGO (Border Report) — The U.S. State Department on Wednesday issued a travel advisory for American travelers heading to Mexico, warning them of “high-risk crime and kidnapping.”

The travel advisory follows a weekend of vandalism, looting and other crimes in Northern Baja California, including the city of Tijuana, as well as the border city of Juarez, Chihuahua.
