Calling it a “credible terrorist threat,” President Barack Obama said apparent explosive material was found on two U.S.-bound packages from Yemen, triggering searches of flights with other packages from Yemen and an investigation into whether al-Qaida was behind a new terror plot.
Sources told NBC News that both packages contained toner cartridges with wires and white powder. The devices were found in Britain and Dubai last night.
“An initial examination of those packages has determined that they do apparently contain explosive material,” Obama told reporters.
