FILE - This undated file photo released Oct. 31, 2010 by Saudi Arabia's Ministry of Interior, purports to show Ibrahim Hassan al-Asiri. Al-Asiri constructed the first underwear bomb and two others that al-Qaida built into printer cartridges and shipped to the U.S. on cargo planes in 2010. U.S. bomb experts are picking apart a sophisticated new al-Qaida improvised explosive device, a top Obama administration counterterrorism official said Tuesday, to determine if it could have slipped past airport security and taken down a commercial airplane.
