WASHINGTON - Passengers at some overseas airports that offer U.S.-bound flights will be required to power on their electronic devices in order to board their flights.
The Transportation Security Administration says it's requiring some overseas airports to have passengers turn on devices such as cellphones before boarding. It says devices that won't power up won't be allowed on planes, and those travelers may have to undergo additional screening.
American intelligence officials have been concerned about new al-Qaida efforts to produce a bomb that would go undetected through airport security. There is no indication that such a bomb has been created or that there's a specific threat to the U.S.
Homeland Security Secretary Jeh (jay) Johnson recently ordered the TSA to call for extra security measures at some international airports with direct flights to the United States.
