Kremlin Opponent Navalny Was Killed With Toxic Agent, UK Says
The Russian opposition leader Alexei Navalny was assassinated using a potent nerve agent, specifically epibatidine, according to an announcement by the United Kingdom on February 14, 2026. The revelation adds a new layer to the scrutiny surrounding Navalny’s death in a Russian penal colony last year, and underscores the escalating tensions between Russia and the West.
British Foreign Secretary Iveta Cooper stated at the Munich Security Conference that “only the Russian government had the means, motive and opportunity to employ this deadly toxin against Alexei Navalny while he was in custody in Russia.”
Epibatidine is a highly toxic chemical compound found in the skin of poison dart frogs native to South America. The substance has a powerful effect on the nervous system.
The findings were corroborated by a joint statement released on Saturday, February 15, 2026, from France, Germany, the Netherlands, Sweden, and the United Kingdom. The statement affirmed that analyses of samples taken from Navalny “conclusively confirm the presence of epibatidine.”
“To carry out this attack, only the Russian state had the means and motive, and disregard for international norms,” the joint statement read. The countries indicated they would report the violation to the Chemical Weapons Convention Organization.
Navalny, a prominent critic of Russian President Vladimir Putin, died on February 16, 2024, while serving a 19-year sentence in the “Polar Wolf” penal colony in the Yamal Nenets Autonomous Okrug region of Russia. His supporters and family have directly blamed Putin for his death.
The accusation of using a sophisticated and rare toxin raises serious questions about the methods employed by the Russian government and could further isolate Moscow on the international stage.
