The U.S. State Department has warned citizens about potential risks to travel in Europe after Tuesday's airport and subway bombings in Brussels.
Airport security has been stepped up across the country, including here in Nashville.

Officials with Nashville International Airport were already expecting back-ups at security checkpoints on Wednesday and Thursday.
Lines were expected to be long due to Spring Break travelers and those flying out of conventions from Nashville this week.
The additional security will also affect flight check-in.
Following the Brussels attacks, there was a noticeable difference at BNA, with several police officers watching over the facility's entrance and the airline check-in areas.
Meanwhile, the State Department said "terrorist groups continue to plan near-term attacks throughout Europe, targeting sporting events, tourist sites, restaurants and transportation."
It has advised U.S. citizens to "exercise vigilance" in public places or on mass transportation, and advising "particular caution" during religious events or large events.
The Obama Administration is taking precautions but right now the government said there is no specific credible threat to a similar plot in the U.S.
