Five European governments on Saturday announced their investigation determined Russian opposition leader Alexei Navalny was poisoned, contradicting Moscow’s claims he died of natural causes. 

The United Kingdom, Sweden, France, Germany, and the Netherlands said they “are confident” Navalny was poisoned by epibatidine, a toxin found in poison dart frogs in South America. Officials said in a joint statement that they came to the conclusion based on analyses of samples from Navalny, who died in February 2024 while imprisoned at an Arctic penal colony in Russia.
