The U.S. State Department reminded travelers to avoid going to parts of Mexico as four Americans were kidnapped in Matamoros last week – two of whom were killed while the other two returned to the U.S. on Tuesday.

The reminder came just days before college students head off to tropical destinations like parts of Mexico for Spring Break.
