Five European nations have jointly accused Russia of assassinating opposition leader Alexei Navalny with a lethal nerve agent derived from poison dart frogs, a claim made public Saturday. The governments of the United Kingdom, France, Germany, Sweden, and the Netherlands stated that laboratory analysis conclusively identified epibatidine, a toxin found in the skin of Ecuador’s poison dart frogs, in samples taken from Navalny’s body.
The accusation, delivered during the Munich Security Conference, marks a significant escalation in international condemnation of the Kremlin following Navalny’s death in a remote Arctic penal colony in February 2024. “Only the Russian state had the means, motive and opportunity to deploy this lethal toxin to target Navalny during his imprisonment in a Russian penal colony in Siberia, and we hold it responsible for his death,” a joint statement released by the five countries declared. Epibatidine is not naturally found in Russia, and its presence in Navalny’s system has “no innocent explanation,” the statement added.
The UK Foreign Secretary, Yvette Cooper, described the poisoning as “barbaric” and stated that Russia viewed Navalny as a threat. “By using this form of poison the Russian state demonstrated the despicable tools it has at its disposal and the overwhelming fear it has of political opposition,” she said. The UK announced it would report Russia to the Organisation for the Prohibition of Chemical Weapons (OPCW), alleging a violation of the Chemical Weapons Convention (CWC).
Navalny, President Vladimir Putin’s most prominent political opponent, had been serving a 19-year prison sentence on charges widely considered to be politically motivated. He had long campaigned against official corruption and organized large anti-Kremlin protests. His widow, Yulia Navalnaya, responded to the findings on X, stating the toxin “causes paralysis, respiratory arrest, and a painful death.” She added, “I was certain from the first day that my husband had been poisoned, but now there is proof: Putin killed Alexei with [a] chemical weapon.” Navalnaya called for Putin to be held accountable for “all his crimes.”
The accusation comes amid a history of alleged Kremlin involvement in poisoning attacks against its critics. The death of Alexander Litvinenko in London in 2006, caused by radioactive polonium, and the 2018 nerve agent attack on former spy Sergei Skripal in Salisbury, UK, have cemented Russia’s reputation for employing toxins to silence dissent. A previous attempt to poison Navalny in 2020, using the Novichok nerve agent, likewise drew international condemnation.
The UK Foreign Office stated it had worked with partners in Sweden, France, the Netherlands, and Germany to uncover the truth surrounding Navalny’s death. The timing of the announcement, coinciding with the Munich Security Conference – the same forum where news of Navalny’s death was initially reported two years ago – was deliberate, according to officials. At the 2024 conference, Navalnaya delivered a brief address vowing that those responsible for her husband’s death would be brought to justice.
The UK has previously led efforts to expose what it considers Russia’s utilize of poison against its opponents, including the Skripal case. The UK also maintains that Russia has not fully destroyed its chemical weapons stockpile, as claimed in 2017, and has not renounced biological weapons, violating its obligations under the biological and toxin weapons convention.
The United States was not among the countries making the claim regarding the specific toxin used in Navalny’s death. The Kremlin has not yet issued a formal response to the latest accusations.
