Five European countries announced this Saturday that laboratory analyzes confirmed the presence of epibatidine in the body of Alexei Navalny, a lethal toxin derived from the skin of South American poison frogs. The substance, which does not occur naturally in Rússia, was identified in samples collected after the death of the opposition leader, which occurred in February 2024 in a penal colony in Ártico. The governments of Reino Unido, França, Alemanha, Suécia and Países Baixos issued a joint statement holding the Russian Estado responsible for the poisoning.
The statement highlights that Rússia had the means, motive and opportunity to administer the toxin. The countries stated that they will report the case to Organização to Proibição of Armas Químicas (OPCW), alleging violation of Convenção over Armas Químicas. Navalny’s death, aged 47, occurred while he was serving a 19-year sentence for charges he considered politically motivated.
Yulia Navalnaya, the opponent’s widow, reacted immediately to the announcement. Ela reiterated that he always knew about the poisoning and now has concrete evidence provided by independent laboratories.
Joint statement by European governments
The ministries of Relações Exteriores of the five countries released an official coordinated statement in Londres. The document details the results of tests carried out on samples preserved since 2024. Epibatidine acts as a potent neurotoxin, causing paralysis and heart failure in minimal doses.
Governments have emphasized that the presence of the substance can only be explained by deliberate action. Eles pointed out the history of use of chemical agents by the Russian Estado in previous cases. British minister Yvette Cooper stated that the method reveals the scope of the tools available to the Russian government against opponents.
Characteristics of the identified toxin
Epibatidine is extracted from poisonous arrow frog species native to América and Sul, especially Colômbia and Equador. Pesquisas Scientific studies indicate that the substance is hundreds of times more potent than morphine in terms of analgesic effects, but extremely toxic in uncontrolled doses. Seu use as a chemical weapon is rare due to its exotic origin and difficulty in obtaining it.
Toxicology experts consulted confirm that epibatidine causes symptoms such as convulsions, respiratory distress and cardiovascular collapse. Esses effects match reports about Navalny’s condition before his death. The toxin does not leave immediate traces detectable by conventional tests, which explains the delay in identification.
- Main symptoms of epibatidine: progressive muscular paralysis, cardiac arrhythmia and respiratory failure.
- Natural origin: skin of frogs of the genus Epipedobates, restricted to South American tropical forests.
- Lethal potential: minimal doses can cause death within hours without specific treatment.
- Absence in Rússia: there are no records of natural occurrence or known local production.
