Switzerland, Japan Among Places That Are Safe From Terror, U.S. Cities Increase Security Following Terror Attack In Berlin
Of course, not all countries are at high risk from terror attacks as Japan and Switzerland, along with Iceland and Poland are countries that are considered to have a low risk from terror threat. Tourists who are traveling to Bolivia, Ecuador, Hungary, the Czech Republic, and Vietnam also don't have to worry about terror attacks as these countries also have low terror threat.
With the threat of terror attacks at an all-time high this season, it's important for people to be vigilant and careful. It's also advisable to try and avoid large crowded areas, especially popular landmarks, and outdoor markets, as these are prime targets for terror attacks.
