SECRET MI5 FILES have revealed how Nazi forces plotted to kill British troops with poisoned chocolate and sabotaged cigarettes as part of a campaign of terror in Allied Europe.

Female agents were ordered to murder senior Allied commanders using microbes in handbag mirrors, the Telegraph reports.

The documents show how the Nazi security service planned subversion operations in Allied countries by deploying four agents into France two months before the end of the war in 1945. The group was dropped behind enemy lines before the aircraft carrying them was shot down.

The agents had been carrying tube of Bayer’s aspirin tablets, one or two of which contained poison, according to the papers. The plan was to offer a target sabotaged cigarettes that would cause a headache – and then pass the target a painkiller. Not all of the pills were poisoned in order for the agent to take one to detract suspcion, the Daily Mail reports.

The document stated: “The agent was also to smoke one of the cigarettes and would take one of the real aspirins from the tube”.

Powder was also found in the agents’ possession after they were apprehended by Allied forces. This power contained ground-up glass mixed with poison, which would have been smeared onto door handles, books or desks in the hope that the substance would enter the target’s bloodstream.

The documents also revealed how Nescafe and sugar were also contaminated, and Allied troops were warned about Nazis wearing swastika-shaped belt buckles that contained a mini-pistols capable of firing two shots.
