Alexandr Litvinenko

Alexandr Litvinenko was a former KGB agent and outspoken critic of the Russian government, particularly of Vladimir Putin. He gained international attention after he was poisoned with a radioactive substance, polonium-210, in London in 2006, which led to his death. Litvinenko's case highlighted the risks faced by those who oppose the Russian regime and raised serious questions about state-sponsored assassinations. His dramatic demise has become a symbol of the dangers associated with dissent in Russia.
