Terror chiefs are also targeting fanatics who suffer other lethal blood diseases such as hepatitis and dengue fever in order to increase their "kill rate" from an explosion. The chilling new threat is revealed in papers distributed to British military camps in Iraq and across Europe.
Under the heading "HIV/Hepatitis" the document states: "There is evidence that terrorists are deliberately recruiting volunteers with diseases that are spread by blood transference."
Experts have found that bones and other blood-spattered fragments from a suicide bomber could penetrate the skin of a victim 50 metres away and infect them.
In the papers (part of which is summarised above) soldiers are warned to wear special protective clothing when on guard duty or if they have to deal with casualties in the event of an attack.
All bases must also have snipers hidden behind blast-proof defences ready to take out would-be suicide bombers. The guidelines were issued following the 7/7 London bombings which left 52 dead and injured hundreds more.
Spy chiefs have also examined other attacks, including a car-bombing on the Black Watch in central Iraq which killed three soldiers a year ago.
Last night an MoD spokesman confirmed that bases had been made aware of the new threat.
He added: "The Army go to great lengths to prepare our soldiers for every eventuality."
