As summer approaches and many Americans plan to jet-set across the country and world on vacation, the U.S. Department of State is warning travelers to take caution while visiting a popular destination.

On May 23, the department reissued a level 2 travel advisory for travel to Italy, urging travelers to “exercise increased caution” due to “terrorism.”

“There is risk of terrorist violence, including terrorist attacks and other activity in Italy,” the warning read.

The advisory warns that terrorists “may attack with little or no warning” and encourages Americans to be aware of common targets, including tourist spots, transportation centers, shopping malls and markets, local government buildings, hotels, clubs, restaurants, religious sites, parks, sports and cultural events, schools, airports and public areas.

The State Department said they review travel advisories on a regular basis and would update alerts “any time conditions change substantially.”

Level 1 and 2 advisories are reviewed every 12 months, while levels 3 and 4 are reviewed at least every six months, the department added. 

A State Department spokesperson told Fox News Digital that there is “no higher priority than the safety and security of U.S. citizens overseas.”

“We take seriously our commitment to provide U.S. citizens with clear, timely, and reliable information about every country in the world so they can make informed travel decisions,” a State Department spokesperson told Fox News Digital. “The Department of State routinely updates our Travel Advisories and destination information pages based on a comprehensive review of all available safety information and ongoing developments.” 

Italy is considered one of the world’s most culturally important countries and is home to 54 World Heritage Sites, the most in the world. Italy’s political system is also traditionally volatile, and, as of 2018, saw a populist coalition rise to power.
