Al-Qaeda fanatics may be planning a horrific 'Frankenbomber' suicide attack by implanting explosives into a human body.
Defence analysts logged conversations between users of a online forum in which Muslim extremists debate terrorism methods which could beat new US aviation security checks.
The alarming posts included one by a user who claimed to be a surgeon, promising a ‘new kind of terrorism’.
Worrying attack: A Saudi Prince was injured in a suicide bombing in which the would-be killer carried explosives inside his body
The forum discussion comes as US passengers reacted angrily to ‘intrusive’ body searches involve pat-downs and scanners in a security crackdown.
Such searches would not detect a ‘Frankenbomber’ implanted with explosives, it is believed.
Mark Rossini, a former senior FBI counter-terror expert told the New York Daily News: ‘In the same way that drug smugglers have placed bags of narcotics in the body cavities of animals and had people ingest condoms filled with drugs, it would not be out of the realm of Al Qaeda operational planners to conceive of such a technique.
‘No technique is off-limits to Al Qaeda to achieve its destructive goals.’
In August last year, Saudi Prince Mohammed Bin Nayef was injured when a suicide bomber with explosives carried inside his body managed to breach security and detonate the device.
