Investigators were studying an explosive device Tuesday that they say terrorists in Yemen crafted to slip past airport metal detectors and onto an airplane bound for the United States.
U.S. intelligence agents thwarted the plot two weeks ago after receiving a tip from Saudi Arabia, a source familiar with the operation said Tuesday. Authorities have said airline passengers were never in danger and that the would-be bomber no longer poses a threat.
