WASHINGTON - The U.S. State Department is warning citizens about potential risks to travel in Europe after Tuesday's airport and subway bombings in Brussels.
The department says "terrorist groups continue to plan near-term attacks throughout Europe, targeting sporting events, tourist sites, restaurants and transportation."
It is advising U.S. citizens to "exercise vigilance" in public places or on mass transportation, and advising "particular caution" during religious events or large events.
