VX, a chemical warfare agent labeled as a weapon of mass destruction by the United Nations, has been identified as the means that killed Kim Jong-nam last Monday.
Similar in appearance to engine oil, simply 10 milligrams—or one drop—of the nerve agent is enough to kill a person in minutes. Symptoms of contact with VX include convulsions, loss of consciousness, paralysis, and respiratory failure.
According to Reuters on Friday, Malaysian police identified traces of VX in the deceased body of Jong-nam, the half-brother and political opponent of leader Kim Jong-un of North Korea. The difficult-to-produce and rare chemical had infiltrated Jong-nam’s body upon contact by two women who used their bare hands, according to authorities.
