An attempt is being made by the Taliban to infect British troops with HIV, The Sun reveals.
Hypodermic syringes are hidden below the surface pointing upwards to prick bomb squad experts as they hunt for devices.
The heroin needles are feared to be contaminated with hepatitis and HIV. And if the bomb goes off, the needles become deadly flying shrapnel.
The tactic has been used in the Afghan badlands of Helmand, and was exposed by Tory MP and ex-Army officer Patrick Mercer.
