Russian opposition leader Alexei Navalny was fatally poisoned with a toxin from Ecuadorian dart frogs that is 200 times stronger than morphine — a “despicable” killing which could only have been carried out by Russia, five Western nations and the activist’s widow, Yulia Navalnaya, said Saturday. Navalny, 47, died Feb. 16, 2024 in an Arctic penal colony, sparking outrage around the world. Foreign ministers from the United Kingdom, Germany, Sweden, and the Netherlands joined Navalnaya as she made the revelation to reporters at the annual Munich Security Conference — the same event where she announced his death two years earlier.
