Sana'a, capital of Yemen
A young man passed through Heathrow's airport security without a hitch. In his backpack he had a few books and a diabetic kit with a syringe inside. It's unusual for someone so young to be an insulin-dependent diabetic, but not unheard of.
Safely on board, the 747 takes off for Chicago and somewhere over Ireland, he goes to the toilet. He injects the insulin into his stomach and quickly returns to his seat. And then the plane blew up. Flight No 4201 with 416 passengers on board disintegrated in mid air and there were no survivors. The "insulin" he injected was the liquid chemical explosive triacetone triperoxide (TATP) which detonated the plastic explosive in his stomach.
This scenario didn't happen but it could have. A suicide bomber hid a bomb inside himself last year and tried to kill Afghanistan's head of security Asadullah Khalid. Having survived two assassination attempts, Khalid was suspicious when a man from a peace envoy asked to see him. The visitor was taken to the basement and ordered to strip in front of CCTV cameras. When nothing was found, he was presented to Khalid and at that exact moment, he blew up. Khalid survived but continues to suffer from severe internal injuries and wounds to his hands and legs.
Al Qaeda's master bomb maker Ibrahim al-Asirir has invented a fool-proof way of killing us, the enemy, by concealing explosives inside the body that can't be detected by sophisticated airport scanners. They plan to surgically implant bombs in the abdominal cavity, buttocks and female breasts.
Last Friday the US said they would close two dozen embassies and consulates across the Middle East and North Africa and issued a travel warning to their people. France and Germany have closed their embassies in Yemen and the British have also shut up shop and urged their people to leave.
But Australia is "still reviewing the situation" and has no plans to close any embassies. I just hope they know what they're doing.
