New discovery lifts the lid on the tests that reveal the true horror of the so-called ISIS caliphate

ISIS has tested deadly poisons on prisoners in Nazi-style experiments in a bid to develop chemical weapons which could be used to contaminate Britain’s food supplies.

A cache of documents record the death cult’s use of “human guinea pigs” who died testing at least two chemical agents, reports The Times.

The papers were found hidden at Mosul University by Iraqi special forces after it was recaptured from the retreating jihadists.

British and US forces have verified the records as bona fide Isis papers.

They document experiments on prisoners using pesticides and nicotine.

The nightmarish scenario is reminiscent of trials conducted by evil Nazi doctor Josef Mengele on concentration camp inmates during World War 2.

Hamish de Bretton-Gordon, a British chemical weapons expert, described Isis testing to the Times on humans as “almost holocaust type”.

He said: “This is a horrifying throwback to the Nazis who would test nerve agents on live humans.

“During the Second World War, the Nazis conducted thousands of deadly experiments with mustard gas on prisoners at Sachsenhausen concentration camp, near Berlin.”
