Americans warned popular travel routes this summer could carry crime and kidnapping risks

The advisory remains at a "Level 2: Exercise Increased Caution" warning, citing concerns about terrorism, crime and kidnapping.

Mexico is set to host matches in Mexico City, Guadalajara and Monterrey during the tournament.

Risk levels vary significantly across the country.

Six states remain under a Level 4 "Do Not Travel" advisory: Colima, Guerrero, Michoacán, Sinaloa, Tamaulipas and Zacatecas.

Several additional states, including Baja California, Chihuahua, Guanajuato and Jalisco, are classified as Level 3, meaning Americans should reconsider travel.

"Fleeing or ignoring instructions can lead to you being hurt or killed," the advisory states.

Officials encourage Americans planning to attend World Cup matches to review the latest guidance from the U.S. Embassy before traveling.
