Name Your Poison — Exotic Toxins Fell Kremlin Foes

The sudden illness in Britain of a Russian man convicted of spying for London has drawn comparisons with another poisoning in the United Kingdom — the assassination in 2006 of Russian former-spy-turned-Kremlin-critic Aleksandr Litvinenko, who was found by a British public enquiry to have been poisoned by Russian state agents.

Sergei Skripal, a 66-year-old former Russian Army colonel, and his 33-year old daughter Yulia Skripal, were critically ill at a Salisbury hospital on March 6 — two days after they collapsed unconscious on a bench in Salisbury from what British authorities described as “suspected exposure to an unknown substance.”
