DALLAS (CBSDFW.COM) - It's getting more difficult to find a safe place to travel in Mexico.
The U.S State Department expanded its warning of non-essential travel to 14 states in northern and central Mexico.
Their warning back in April included 10 Mexican states.
The State Department says that U.S. citizens have recently fallen victim to drug-cartel related activity "including homicide, gun battles and kidnapping." according to the State Department website.
