WASHINGTON (CBSNewYork/AP) -- The CIA thwarted a plot by al-Qaida's affiliate in Yemen to destroy a U.S.-bound airliner using a more sophisticated underwear bomb to coincide with the anniversary of Osama bin Laden's killing, CBS News has learned.
The plot involved an upgrade of the underwear bomb that failed to detonate aboard a jetliner over Detroit on Christmas 2009. The new bomb was also designed to be used in a passenger's underwear, but this time al-Qaida developed a more refined detonation system, U.S. officials told the Associated Press.

Officials, including Long Island Rep. Peter King said the device did not contain metal.
"It was a non-metallic device. It's a bomb, explosive device -- a plastic-type material. It was intended for an American-bound airline," King told 1010 WINS, emphasizing that the bomb never made it on a plane.
The FBI is examining the latest bomb to see whether it could have passed through airport security and brought down an airplane, officials told CBS News. It was not clear whether new body scanners used in many airports would have detected it.
"The bomb is in our possession. It's being analyzed by the bomb experts -- specifically the FBI, the Department of Homeland Security and it's in our possession and we're trying to find the exact nature of the bomb -- how it would have worked, how it would have gotten around our detectors," King said.
Authorities said the would-be suicide bomber, based in Yemen, had not yet picked a target or bought a plane ticket when the CIA stepped in and seized the bomb, officials said. It's not immediately clear what happened to the alleged bomber.
White House spokeswoman Caitlin Hayden said President Barack Obama learned about the plot in April and was assured the device posed no threat to the public.
"The president thanks all intelligence and counter terrorism professionals involved for their outstanding work and for serving with the extraordinary skill and commitment that their enormous responsibilities demand," Hayden said.
The operation unfolded even as the White House and Department of Homeland Security assured the American public that they knew of no al-Qaida plots against the U.S. around the anniversary of bin Laden's death. The operation was carried out over the past few weeks, officials said.
"We have no credible information that terrorist organizations, including al-Qaida, are plotting attacks in the U.S. to coincide with the anniversary of bin Laden's death," White House press secretary Jay Carney said on April 26.
On May 1, the Department of Homeland Security said, "We have no indication of any specific, credible threats or plots against the U.S. tied to the one-year anniversary of bin Laden's death."
The AP learned about the thwarted plot last week but agreed to White House and CIA requests not to publish it immediately because the sensitive intelligence operation was still under way. Once officials said those concerns were allayed, the AP decided to disclose the plot Monday despite requests from the Obama administration to wait for an official announcement Tuesday.
U.S. officials, who were briefed on the operation, insisted on anonymity to discuss the case, which the U.S. has never officially acknowledged.
It's not clear who built the bomb, but, because of its sophistication and its similarity to the Christmas bomb, authorities suspected it was the work of master bomb maker Ibrahim Al-Asiri.
Al-Asiri constructed the first underwear bomb and two others that al-Qaida built into printer cartridges and shipped to the U.S. on cargo planes in 2010.
Both of those bombs used a powerful industrial explosive. Both were nearly successful.
Al-Qaida has suffered significant setbacks as the CIA and the U.S. military focus more on Yemen. On Sunday, Fahd al-Quso, a senior al-Qaida leader, was hit by a missile as he stepped out of his vehicle along with another operative in the southern Shabwa province of Yemen.
Al-Quso, 37, was on the FBI's most wanted list, with a $5 million reward for information leading to his capture. He was indicted in the U.S. for his role in the 2000 bombing of the U.S.S. Cole in the harbor of Aden, Yemen, in which 17 American sailors were killed and 39 injured.
Al-Quso was believed to have replaced Anwar al-Awlaki as the group's head of external operations. Al-Awlaki was killed in a U.S. airstrike last year.
