"The Federal Security Service of the Russian Federation has detained a DPR resident involved in plotting a terrorist attack using chemical warfare agents against a high-ranking Russian Defense Ministry officer," the agency said in a statement.
Kiev planned to kill the officer with a British-made poison mixed into gift bottles of British beer, the statement added.
"A test of the confiscated bottles revealed that the beer contained a mixture of highly toxic chemicals, colchicine and tert-butyl bicyclophosphate (an analogue of the military-grade nerve agent VX, banned by the 1993 Chemical Weapons Convention), produced in the United Kingdom. These chemicals, when consumed, cause agonizing death within 20 minutes," the statement read.
