[2][3] Assisted by his older brother, Ibrahim al-Asiri, he had hidden a pound (about 0.45 kg) of PETN plastic explosives in his rectum and anal canal, which security experts described as a novel technique.
[7] The Saudi Gazette reported on October 22, 2009, that a Yemeni named Rayed Abdullah Salem Al Harbi assisted Asiri in preparing for his suicide mission.
[8] According to the American defense official Michael G. Vickers, a laparoscopic surgeon had helped Abdullah's brother Ibrahim al-Asiri implant explosives inside suicide bombers.
[10][11][12] According to The Daily Mirror in the UK, security officials at the British Secret Intelligence Service asserted that female bombers could travel undetected carrying the explosive chemicals in otherwise standard breast implants.
For example, in the 1957 novella "Run for the Stars" by Harlan Ellison, the drug-addicted protagonist has a bomb implanted in his abdomen to delay an advancing alien army, making him an involuntary suicide bomber.
