TSA Announces New Security Rules for Overseas Flights

TSA screeners at overseas airports may start asking U.S.-bound passengers to power on their electronics for safety.

It's an effort to look for new kinds of explosive devices.

If it can't power on, the device will not be allowed on board and the traveler may undergo additional screening.

The new precautionary measure is aimed at limiting the terror threat from the Middle East and Europe.

TSA is asking for the cooperation of foreign governments to provide security at overseas airports.

The agency says the new rules have not been prompted by any specific threat.
