The State Department issued an alert on Monday to US citizens traveling to Europe about a “heightened risk of terrorist attacks,” particularly over the holiday season. “Have an emergency plan of action ready,” the US urged according to NBC.
"Credible information indicates the Islamic State of Iraq and the Levant (ISIL the U.S. gov't acronym for ISIS or Da'esh), al-Qaeda, and their affiliates continue to plan terrorist attacks in Europe, with a focus on the upcoming holiday season and associated events," the travel advisory read.
