Underwear bombs, implanted bombs an al-Asiri strategy

WASHINGTON,
May 1 (Reuters) - U.S. and allied officials said they are increasingly
concerned that doctors working with al Qaeda's Yemen-based affiliate will
implant bombs inside living militants in order to try to circumvent airport
security measures and bring down aircraft.
Earlier
this year, a missile fired by a CIA-operated drone killed a Yemeni doctor who
had devised medical procedures which could be used to surgically plant
explosive devices in humans, several U.S. officials told Reuters.
However,
another individual, the expert bomb-maker who came up with this tactic survived
a similar missile attack last year. Counterterrorism agencies believe he is
still engaged in active plotting against U.S. and other Western targets.
Moreover,
three U.S. officials said counter-terrorism agencies report that other doctors
in Yemen are prepared to surgically load bombs into the organs of militants.
The
possibility of implanted bombs has been a concern for U.S. officials since at
least 2009, when two incidents occurred involving militants who had spent time
with leading figures of Yemen-based Al Qaeda in the Arabian Peninsula (AQAP).
In
August 2009, a Saudi militant who had spent time in Yemen unsuccessfully tried
to assassinate Prince Mohammed bin Nayef, Saudi Arabia's counter-terrorism
chief, with what authorities initially believed was a bomb secreted in his anal
cavity.
Authorities
determined the bomb was virtually identical to a one which Umar Farouk
Abdulmutallab, a Nigerian militant who had been studying Arabic in Yemen, used
to try to blow up a Detroit-bound airliner on Christmas Day 2009.
Both
Abdulmutallab's bomb and the bomb used in the failed attack on Nayef turned out
to have been sewn into the would-be bombers' underwear, rather than implanted
inside body organs or cavities.
These
incidents sparked concern among U.S. and western counter-terrorism agencies
that implanted bombs might be a more effective way for militants to evade
airport security devices including X-ray machines and metal detectors.
MORE
OR LESS POWERFUL?
After
the failed attack on Prince Nayef, three U.S. agencies examined the threats
which bombs secreted in clothing or inside the body could pose to aviation
security.
According
to U.S. officials, the research suggested that a bomb hidden inside a body
cavity or organ would be less likely to jeopardize the safety of an airplane
than a bomb hidden under clothing. Much of the force of the bomb would be
absorbed by exploding body tissue, likely killing the bomber but causing little
structural damage to an aircraft.
By
contrast, the explosive force of a bomb hidden under clothing alone would be
more likely to cause potentially catastrophic damage to an airplane if
detonated in flight, officials said.
Officials
said that in response to the possible deployment of implanted bombs, efforts
were being made to adjust airport security, including the body scanners and
metal detectors now used, to try to spot potential threats.
AL-ASIRI
CONNECTION
Officials
said that one reason for concern is the continuing role of Saudi bomb-maker
Ibrahim Hassan al-Asiri, now regarded by U.S. and European authorities as one
of the more dangerous and imaginative AQAP operatives presently at large.
Counterterrorism
experts attribute the original invention of the two tactics to Asiri, and it
was his brother who wore the underwear bomb and died while attempting to kill
Prince Nayef.
Officials
acknowledge initial reports were wrong that Asiri was killed in the same
sequence of drone attacks which resulted in the death last year of Anwar al-Awlaki,
a U.S.-born militant Yemeni preacher.
ABC
News reported on Monday that American and European officials feared al Qaeda
may soon try to attack U.S.-bound aircraft using explosives implanted in the
bodies of militants. ABC reported that due to this concern, security had been
stepped up at some British and European airports and some Federal Air Marshals
may have been redeployed.
