No additional security measures are being taken at Sky Harbor Airport -- despite the terror attacks in Brussels.
A TSA official said that could change though -- depending on what develops throughout the day.
ABC News reports that Homeland and FBI officials are monitoring the unfolding events in Brussels closely and Attorney General Lorretta Lynch has been notified of the attacks.
What terrorism experts are most concerned about will be copy cats -- who are inspired by what they're seeing in Brussells.
That is what inspired the three Phoenix men, Elton Simpson, Nadir Soofi and Abdul Kareem to attack an anti-Mohammed event in Texas last May. The trio were allegedly encouraged after watching the Charlie Hebdo attacks in Paris.
Simpson and Soofi were killed during their attack.
Kareem was convicted last week for helping plan Simpson and Sooif plan their attack.
