Passengers boarding flights to the U.S. from overseas may now have to turn on their electronic devices during security screening. However, if it doesn't turn on, then the device is not allowed on board.
As previously reported, this new airport safety measure is a result of stricter security for flights heading to the United States, especially in regards to new terrorists threats from the Middle East and Europe.
According to CNN, "Our job is to ... try to anticipate the next attack, not simply react to the last one. And so we continually evaluate the world situation, and we know that there remains a terrorist threat to the United States, and aviation security is a large part of that," Secretary of Homeland Security Jeh Johnson explains to NBC's "Meet The Press."
The Transportation Security Administration is testing for explosive devices. If the passenger's device does not turn on, then they will face additional screening.
Additional updated security tactics remain unconfirmed at this time.
