WASHINGTON (AP) -- Over the past three years, al-Qaida bomb makers in Yemen developed three clever devices in hopes of attacking airplanes over the U.S.
The first was the underwear bomb that fizzled over Detroit on Christmas 2009. Then in 2010 terrorists hid bombs inside printer cartridges and got them on board cargo planes. Authorities found and defused them in the nick of time.
Last month, al-Qaida completed a sophisticated new, nonmetallic underwear bomb -- and unwittingly handed it over to the CIA.
Officials speaking on condition of anonymity because they weren't authorized to discuss the operation said Tuesday the man al-Qaida entrusted with the device actually was a double agent working with the CIA and Saudi intelligence agencies. He delivered the bomb to the U.S. government and handed al-Qaida its latest setback.
