The CIA has prevented what they called an ambitious plot by Al Qaeda's affiliate in Yemen. The plot was an upgrade of the underwear bomb that failed to detonate on an airliner over Detroit in December of 2009.
The new bomb was also designed to be used in a passenger's underwear. U.S. Officials say Al Qaeda developed a more refined detonation system.
The FBI has examined the device to see if it could pass through airport security systems. The device did not contain metal, but it's not clear whether or not it could be detected by new body scanners.
Officials said the would-be bomber had yet to pick a target, buy a plane ticket, let alone enter a U.S. airport before officials seized the bomb. They have assured the public it poses no threat. No changes have been made to airport security procedures.
