British military intelligence agency MI5 has uncovered evidence that terrorist groups have begun planning attacks with bombs surgically implanted inside a human body.
The bombs would be surgically implanted into men's buttocks and women's breasts, and could evade traditional airport security. According to The Daily Mail, MI5 became aware of the threat due to chatter on 'Arab websites' earlier this year.
The Daily Mail article reports:
Experts said the explosive PETN (Pentaerythritol Tetranitrate) would be placed in a plastic sachet inside the bomber's body before the wound was stitched up like a normal operation incision and allowed to heal.
A shaped charge of 8oz of PETN can penetrate five inches of armour and would easily blow a large hole in an airliner.
According to reports, the move towards bombs being placed inside bodies may be gaining speed. In August 2008, Abdullah al-Asiri, an al-Qaeda militant, passed through several airline security checks with a bomb hidden in his intestine. He later detonated the bomb with a cell phone signal.
