Explosives hidden "inside" his body

I read this BBC report with a sense of 'where on earth did he hide the explosives' but all became clear at the end, I think!

"Security and intelligence experts are deeply worried by a new development in suicide bombing, the BBC has learned.

It has emerged that an al-Qaeda bomber who died last month while trying to blow up a Saudi prince in Jeddah had hidden the explosives inside his body.

...

Experts say it could have implications for airport security, rendering traditional metal detectors "useless".


...

Peter Neuman of Kings College London says the case will be studied intensively, and that there are "tremendous implications for airport security with the potential of making it even more complicated to get on to your plane".

"If it really is true that the metal detectors couldn't detect this person's hidden explosive device, that would mean that the metal detectors as they currently exist in airports are pretty much useless," he said.

The bomber was a Saudi al-Qaeda fugitive who said he wanted to give himself up to the prince in person.

The prince took him at his word and gave him safe passage to his palace.

But there, once he got next to his target, the bomb inside him was detonated.

Miraculously the prince survived with minor injuries, but footage emerging this week shows a sizeable crater in the concrete floor and the bomber's body blown in half.

It is believed the force of the blast went downwards which is why only the bomber died"

How long before we all have to 'bend over' for an 'internal examination' before clearing security at airports?
