UK and Allies Tie Navalny’s Death to Dart-Frog Toxin, Blaming Kremlin

At the Munich Security Conference, Britain and European allies said Navalny was killed by a toxin derived from epibatidine, found on his body two years after his death in a Siberian penal colony, and argued only the Russian state had the means, motive and opportunity to carry out the poisoning. Moscow denied the claim as misinformation. Navalny’s widow welcomed the findings, the UK has informed the OPCW of a suspected Chemical Weapons Convention breach, and the case—following his 2020 Novichok poisoning and 2024 death—continues to heighten tensions over Russia’s political opposition.
