Americans around the globe are on alert thanks to the treat of an attack by al-Queda and the warning will be in effect for weeks to come.
The worldwide travel alert that extends the entire month of August and passengers at John F. Kennedy International Airport are taking notice.
“You have to take it for what it is and be aware when you travel,” said Bob Levine
The alert warns Americans traveling anywhere in the world be on alert for a possible terrorist attack on public transportation and tourist destinations. Bob Levine's daughter Melissa Powell is traveling to the African Nation, Tanzania.
"I've double checked all of my itineraries and I know exactly where I’m going,” said Powell. “I have people to meet up with when I get there -- I know if I have any trouble I’ll have somewhere to go.”
Considered unusually broad, the alerts came just a day after the U.S. State Department announced it planned to close 21 embassies and consulates in 17 countries across the Middle East, North Africa and South-Central Asia this Sunday.
"When our government puts this out – it’s serious.”
Robert Strange is CEO of the security firm Investigative Management Group. He says the warnings and closures are significant.
"Clearly there’s enough information – al-Queda or al-Queda to know exactly where.”
Closer to home, New York Police Commissioner Ray Kelly says patrols were stepped up at transportation hubs and houses of worship.
"It causes concern because it raises everyone’s awareness, but it lacks specific information,” said Kelly.
At JFK, Fox 5 didn't find anyone canceling their flights but Tony Gliatis says that would be like letting the bad guys win.
"It's not going to stop me, no one can stop me. That's what they want to do -- scare everybody."
The U.S. State Department says anyone traveling abroad who uses a smartphone should download the U.S. Embassy app. It provides security updates and locations of nearby consulates.
