In recent days, channels associated with the terrorist army have posted calls for attacks on Europe, Russia and the United States to mark the occasion of the Islamic "Sacrifice Feast" Eid al Adha. In the third part of an English-language series on jihad, IS advised would-be attackers to inject food for sale in markets with cyanide poison. According to Spiesa, the organization has tested these methods on prisons, causing horrifically painful deaths.

"The Islamic State group used prisoners as "human guinea pigs," carrying out chemical weapons experiments in order to plan for attacks against the West, documents found in Mosul have revealed. The papers detailing the tests, which led to the agonizing deaths of prisoners, were discovered at Mosul University in January when it was recaptured by Iraqi special forces. The documents verified by United States and British forces were detailed by The Times in a report published Saturday.

Prisoners had their food and water contaminated by the sprinkling of chemicals found in easily accessible pesticides. The US and Britain now fear that the same methods could be used on a larger scale to contaminate food supplies in the West."

Aside from the obvious death toll, we imagine that a terror attack in an American grocery store would annihilate billions in grocery stock market cap, adding to the industry's Whole Foods Market-inspired woes. Investors who once saw grocers as an oasis in the troubled retail sector are increasingly balking now that Amazon has promised to use sensors and automation to save on staffing costs and undercut rivals on pricing. And the terror threats won't help.
