Russia demands ‘concrete’ proof that it poisoned Navalny with dart frog toxin

Russia is demanding "concrete" proof from European nations regarding their claim that Alexei Navalny was poisoned with epibatidine, a toxin found in dart frogs. Britain, France, Germany, Sweden, and the Netherlands stated that analyses confirmed the presence of this toxin in Navalny's body, asserting that Russia had the means, motive, and opportunity to administer it. Russian Foreign Ministry spokeswoman Maria Zakharova dismissed these accusations as lacking specific details and politically motivated, demanding the handover of concrete data. The Kremlin has rejected the accusations, while Navalny's widow stated that the truth about his death had finally been disclosed.

Navalny's mother says she always knew he was murdered after poison finding

Alexei Navalny's mother, Lyudmila Navalnaya, has stated that the assessment of her son's death as a result of poisoning has validated her long-held belief that he was murdered. The UK and European allies have concluded that Navalny, who died in 2024, was killed using a poison developed from a dart frog toxin, which they believe only Russia had the means, motive, and opportunity to deploy. Navalny, a fierce critic of Russian President Vladimir Putin, died while serving a 19-year sentence for "extremism" in a Siberian penal colony. His widow, Yulia, has marked the two-year anniversary of his death by stating that they have achieved truth and will achieve justice one day too. The Kremlin has rejected the accusations, considering them biased and unfounded. Navalny's funeral was attended by thousands of mourners who defied fears of a police crackdown.

US ‘not disputing’ a ‘troubling’ European report on Navalny poisoning, Rubio says

U.S. Senator Marco Rubio stated that the U.S. is not disputing a European report alleging Alexei Navalny was fatally poisoned with a rare toxin. The report, released by Britain, France, Germany, the Netherlands, and Sweden, identified the toxin as epibatidine, derived from an Ecuadorian dart frog, and implicated Russia. Navalny, a critic of Vladimir Putin, died in a Siberian prison on February 16, 2024, while serving a 19-year sentence. While Britain has directly blamed Russia for Navalny's death and is considering new sanctions, Russia has dismissed the European report. Rubio clarified that the U.S. did not join the report because it was a European-led initiative, but that this did not indicate disagreement with its conclusions.

US ‘not disputing’ European assessment of Navalny poisoning, Rubio says

The United States is not challenging European findings that Alexey Navalny was poisoned with a rare dart frog toxin. Secretary of State Marco Rubio acknowledged the European report as "very troubling" during a visit to Slovakia on Sunday. This follows a joint statement from the UK, France, Germany, the Netherlands, and Sweden accusing Russia of killing Navalny two years prior, citing laboratory analysis finding epibatidine in his body. While the US did not join the statement, Rubio clarified that Washington does not dispute the findings. In response, the UK is considering further sanctions against Moscow, emphasizing coordinated action with European allies to pressure the Russian regime. The announcement increases pressure on the Kremlin and raises the prospect of further coordinated Western action.

UK considers new Russia sanctions after Navalny frog toxin finding

The UK is considering new sanctions against Russia after concluding that Alexei Navalny's death was likely due to poisoning with a dart frog toxin, epibatidine, arranged by the Russian state. The UK, along with allies including Sweden, France, Germany, and the Netherlands, determined that Navalny could not have accidentally ingested the poison, as it is not found in Russia. The five countries have reported Russia to the Organisation for the Prohibition of Chemical Weapons, accusing Moscow of breaching its conventions. The Russian embassy in London denies any involvement. The UK Foreign Secretary, Yvette Cooper, stated that the UK is exploring coordinated action, including increased sanctions, in response to Navalny's death and Russia's ongoing aggression.

What is the ‘dart frog’ toxin, said to be linked to Alexey Navalny’s death?

Five European countries (UK, France, Germany, Sweden, Netherlands) allege that Russia poisoned Alexey Navalny, a Kremlin critic, leading to his death in an Arctic penal colony in February 2024. The countries claim that analyses of samples from Navalny's body revealed the presence of epibatidine, a toxin found in poison dart frogs native to South America. They assert that this finding contradicts Russia's claim that Navalny died of natural causes after a walk. The European nations are calling for Russia to be held accountable for violating international conventions regarding chemical and biological weapons. It remains unclear how the European allies obtained the samples from Navalny's body.
