Foiled plot shows militants seek detection-proof bombs


WASHINGTON (Reuters) - The revelation that militants sought to attack an
airliner with an improved "underwear bomb" in a plot foiled by U.S. and
allied authorities shows their determination to build bombs that can pass
through airport security, U.S. officials said.

The Obama administration said on Monday that authorities in the Middle East
recently seized an underwear bomb which they believe al Qaeda's Yemen-based
affiliate had intended to give to a suicide bomber to blow up an airliner
bound for the U.S. or another Western country.

U.S. officials told Reuters the device was seized within the last 10 days.

The plot was detected in its early stages, and no U.S. airliner was ever at
risk, officials said.

Yet the aborted plot shows that the Yemen-based group, al Qaeda in the
Arabian Peninsula AQAP.L, remains intent on attacking the United States or
its allies, and is continuing to evolve its weapons and tactics.

One official said the latest underwear bomb to be discovered appeared to be
similar to the work of fugitive Saudi militant Ibrahim Hassan al-Asiri, who
U.S. sources believe is a bomb-maker working with AQAP.

U.S. officials said it had design features which were somewhat more
sophisticated than a bomb used in two attempted attacks in 2009.

In the first incident, a man equipped with a bomb in his underwear tried to
attack Prince Mohammed bin Nayef, a senior Saudi Arabian counter-terrorism
official. The bomber killed himself in the attack but the prince survived.

On Christmas Day that year, a Nigerian-born militant who had spent time in
Yemen, Umar Farouk Abdulmutallab, tried to detonate a bomb sewn into his
underpants as his flight from the Netherlands to Detroit began its descent
in U.S. airspace. The device burst into flames but its explosive charge did
not detonate. Abdulmutallab was subdued by fellow passengers and was later
jailed by U.S. authorities.

IMPROVED BOMB MODEL

One official said the device seized in the latest investigation used what
was supposed to be an improved or redesigned mechanism intended to ensure
that the explosive charge detonated.

"While similar, a preliminary review of this device shows that it has some
significant differences from the device used in the Christmas Day attack. It
is clear that AQAP is revamping its bomb techniques to try to avoid the
causes of the failure of the 2009 device," the official added.

Like the bombs used in the two previous attempted attacks, the latest device
was non-metallic, officials said.

Senator Dianne Feinstein, chairman of the Senate intelligence committee,
said: "I congratulate the CIA for thwarting this reported plot by AQAP to
destroy a U.S.-bound airliner using a specific type of bomb that is of new
design and very difficult to detect by magnetometer."

U.S. and European officials said that the newly-revealed plot was part of
continued efforts by AQAP to design devices which could get through airport
security.

A senior U.S. official said the group might be eager to mount an attack
following U.S. operations that killed al Qaeda leader Osama bin Laden and
AQAP's American-born chief Anwar al-Awlaki.

"AQAP is probably feeling pressure to conduct a successful attack to, from
their perspective, avenge the deaths of bin Laden and Awlaki," a senior U.S.
official said.

PLOT NO THREAT TO PUBLIC

Caitlin Hayden, a spokeswoman for the National Security Council, said
President Barack Obama had been informed of the plot in April and had been
regularly updated about it.

"While the President was assured that the device did not pose a threat to
the public, he directed the Department of Homeland Security and law
enforcement and intelligence agencies to take whatever steps necessary to
guard against this type of attack," Hayden said.

U.S. officials declined to say where the underpants bomb was seized or by
whom, but indicated it was either inside Yemen itself or a nearby country.
Several officials stressed that the bomb never made it aboard an aircraft.

A senior U.S. official said: "We disrupted this plot well before it was ever
a threat to the United States."

"We believe AQAP produced the device, and we believe it was intended to be
used by a suicide bomber on an aircraft," the official said, adding: AQAP
remained "committed to striking targets in Yemen, Saudi Arabia, the
Homeland, and Europe."

The FBI said in cooperation with security and intelligence partners overseas
"an improvised explosive device IED.L designed to carry out a terrorist
attack has been seized abroad. The FBI currently has possession of the IED
and is conducting technical and forensics analysis on it."

It said initial investigation showed the bomb was similar to devices used by
al Qaeda in the Arabian Peninsula AQAP.L in attempted attacks on planes and
in assassinations attempts.

U.S. officials said AQAP had also been working to design explosive devices
which could be implanted in would-be suicide bombers and there were doctors
willing to perform the necessary surgery.

They said implanted bombs were more likely that those built into clothing to
defeat airport security though the impact may be weaker.
