The State Department on Tuesday renewed a travel warning to U.S citizens traveling to parts of Mexico, including tourist destinations such as Cancun and Playa del Carmen, due to ongoing homicides in popular areas of the country.

The statement warned U.S. citizens of "gun battles between rival criminal organizations" that have taken place on the streets and in public places during the day and said U.S. citizens have been murdered in carjackings and highway robberies. Most of these crimes occur at night, the department said.

The agency specifically urged Americans to "exercise caution" in Baja California Sur and Quintana Roo, both of which include tourist destinations such as Los Cabos, La Paz, Cancun, Cozumel, and Playa del Carmen.

"Turf battles between criminal groups have resulted in violent crime in areas frequented by U.S. citizens," the State Department warned. "Shooting incidents injuring innocent bystanders have occurred during daylight hours."

The State Department's travel advisory also placed restrictions on travel activity for U.S. government personnel in specific Mexican states.
