In a significant development, five European nations have formally accused Russia of poisoning the opposition leader Alexei Navalny with a rare toxin derived from poison dart frogs, as reported by multiple sources including Al Jazeera and Dawn. This accusation was made public during the Munich Security Conference on February 14, 2026, where the UK, France, Germany, Sweden, and the Netherlands issued a joint statement asserting that analyses of samples from Navalny's body 'conclusively confirmed the presence of epibatidine,' a neurotoxin not found naturally in Russia. The Guardian highlighted that intelligence agencies believe 'only the Russian state had the means, motive, and opportunity' to carry out such an attack, while the UK Foreign Office described it as a 'flagrant violation of the chemical weapons convention.' Navalny, a prominent critic of President Vladimir Putin, died in an Arctic prison in February 2024 while serving a 19-year sentence, and his widow, Yulia Navalnaya, expressed that the findings now provide 'science-proven facts' to support her longstanding claims of murder.
