WASHINGTON — President Barack Obama’s counterterrorism adviser says the discovery of a new plot to take down a U.S.-bound airliner shows the al-Qaida organization remains a threat a year after Osama bin Laden’s killing.

John Brennan tells network morning news shows the discovery of another bomb designed to be worn in the attacker’s underwear resulted from “very close cooperation with our international partners.”

The Associated Press on Monday reported the CIA intercept of a bomb device, citing government officials. Brennan made appearances Tuesday morning on NBC’s “Today” show, ABC’s “Good Morning America” and “CBS This Morning.”

On NBC, he said the “device and the bomber that would use it is no longer a threat.”

The device currently is being analyzed by the FBI, and Brennan said that al-Qaida remains very active in Yemen although it has been “degraded” in Pakistan.
