A series of attacks in Brussels, Belgium has prompted an increase of police presence at Nashville International Airport.
Attackers detonated bombs at the airport and on a metro train beneath the European Union's capital on Tuesday, killing at least 26 people.
The attacks have prompted heightened security for cities across the U.S.

Officials with the Nashville International Airport said there will be an increased presence of airport police -- which is standard procedure whenever there is a terror attack.
“Safety and security is always our number one priority,” said Shannon Sumrall, Corporate Communications Manager at Metropolitan Nashville Airport Authority.
Authorities stressed that no threats have been made against the U.S. at this time.
Passengers at Nashville International Airport said while they're not worried, they are being more observant today.
Airport officials have encouraged passengers to arrive at the airport at least two hours early because of high traffic and increased security.
#TravelAlert: We are expecting heavy passenger volume Wednesday and Thursday due to multiple conventions leaving and Spring Break. Plan to arrive AT LEAST 2 hours before your flight. #packyourpatience
