As someone who travels the world I try my best to stay informed of safety and security wherever I go. The State Department has issued an alert for US citizens to the heightened risk of terrorist attacks in Europe (during the Christmas holiday). They are warning Americans to exercise caution at festivals, markets and events. This warning is in effect until February, 2017.
I always register with STEP (Smart Traveler Enrollment Program) when traveling abroad. I receive alerts and notices directly to my phone – really convenient and timely.
