WASHINGTON (AP) — President Barack Obama's counterterrorism adviser says U.S. officials "have to presume" there might be more potential mail bombs like the ones that were pulled off planes in England and the United Arab Emirates on Friday.
Deputy national security adviser John Brennan says the foiled plot bears the hallmarks of al-Qaida's Yemen branch, and that the terrorists group is "still at war with us and we are very much at war with them."
Brennan notes that because of the continuing threat, the world's largest package delivery companies — FedEx and UPS — have suspended air freight from Yemen. Police in Yemen have arrested a young woman on suspicion of mailing the bombs, which were powerful enough to down airplanes.
Brennan tells NBC's "Meet the Press" that authorities are trying to determine whether the cargo planes were the intended targets. The packages with the explosives were addressed to Chicago-area synagogues.
