British Spies Say Al-Qaeda Now Plans to Use Surgical Bombs

Because hiding bombs in one's underwear didn't work, and airport screening is beginning to get tougher, British spies report that they've found evidence that al Qaeda is planning to insert "surgical bombs" inside people for the first time. Female bombers would have them implanted inside their breasts and male bombers would have the explosive implanted near their appendix or in their buttocks.

The British intelligence agency MI5 said that it believes that the new development was triggered by the introduction of body scanners at airports. It reports that it first got notice of the threat from increasingly vocal "chatter" on Arab web sites.

Apparently, this is how the surgical bomb devices would work:

The explosive PETN (pentaerythritol tetranitrate) would be placed in a plastic sachet inside the bomber's body before the wound is stitched up like a normal surgical incision and allowed to heal. The explosive would be detonated by the bomber using a hypodermic syringe to inject TATP (triacetone triperoxide) through his or her skin into the sachet.
