A look at assassination attempts involving chemicals
Kim Jong Nam, the outcast half brother of North Korea's leader, told medical workers before he died this week that he had been attacked at a Malaysian airport with a chemical spray, according to Malaysian officials. A look at notable assassinations or attempted assassinations involving poison or chemicals:
Litvinenko, a former Russian intelligence agent, was given tea laced with a fatal dose of polonium-210 at a London hotel on Nov. 1, 2006. He died three weeks later of "acute radiation syndrome." In January 2016, a British judge said Russian President Vladimir Putin probably approved a plan by Russia's FSB security service to kill Litvinenko, who had become a Britain-based critic of the Kremlin. Litvinenko made a deathbed statement that he was poisoned on orders from Putin. No one has ever stood trial for the killing, which soured Russian-British relations for years.
Then a Ukrainian presidential candidate, Yushchenko fell ill from a massive dioxin poisoning in September 2004 that knocked him off the campaign trail for weeks and left his face severely pockmarked. Despite the near-fatal illness and several contested runoffs, Yushchenko won the presidency on a wave of popular support that was dubbed the Orange Revolution. In October 2005, the incident was declared to be "an assassination attempt" by Ukraine's Prosecutor General Svyatoslav Piskun.
Agents from Israel's secret intelligence service, Mossad, sprayed a substance believed to be a fentanyl analog into the Hamas leader's ear as he walked down a street in Amman, Jordan, in a botched 1997 assassination attempt. Jordan's King Hussein threatened to hang the captured Mossad agents in a downtown square unless Israel provided an antidote, which it did. Israel's relations with Jordan were shaken by the botched assassination and Prime Minister Benjamin Netanyahu was forced to free a number of Palestinian prisoners in exchange for the agents. After the agents were released, then-Infrastructure Minister Ariel Sharon declared on Israeli television that Israel would try again.
Markov, a Bulgarian dissident, was waiting for a bus at Waterloo Bridge in London in September 1978 when he was jabbed in the thigh with a poisoned umbrella tip in one of the most sensational assassinations of the Cold War. The journalist and harsh critic of Bulgaria's communist regime died four days later. After his death, British government scientists discovered the umbrella had been used to inject a pinhead-sized pellet of the poison ricin into Markov's leg. Though no one has ever been charged with the killing, many suspected the KGB and Bulgarian secret police of involvement.
