Following tips from foreign intelligence services, the CIA agent seized a bomb and thwarted an attack on a U.S. bound airplane intended to go off around the one year anniversary of Osama bin Laden's death. In what the FBI is calling "very similar" about a bomb plot using underwear like the one on board a Delta flight in December of 2009 that landed in Detroit made by the Yemen faction of Al Qaeda, this ugraded bomb also was hidden in underwear.
Officials have described the new bomb as an upgraded version that did not contain any mental to help hide its existence through airport metal detectors.
The discovery of the device indicates al-Qaeda continues to focus on aviation targets, said Homeland Security's Matt Chandler. The department has "no specific, credible information" about an active terrorist plot targeting the U.S., he added.
"What this incident makes clear is that this country has to continue to remain vigilant," Defense Secretary Leon Panetta said.
The upgraded bomb is believed to have been designed by Hassan al-Asiri
