WASHINGTON - US and allied officials said they are increasingly concerned that doctors working with al-Qaida's Yemen-based affiliate will implant bombs inside living terrorists 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 US officials told Reuters.
However, another individual, the expert bomb-maker who came up with this tactic survived a similar missile attack last year. Counter-terrorism agencies believe he is still engaged in active plotting against US and other Western targets.
Moreover, three US officials said counter-terrorism agencies report that other doctors in Yemen are prepared to surgically load bombs into the organs of militants.
