The mother of Russian opposition leader Alexey Navalny said she hopes for justice after several European nations concluded he died from poisoning while imprisoned, a claim strongly rejected by Moscow.
Britain, France, Germany, Sweden, and the Netherlands said Navalny was likely poisoned with epibatidine, a toxin associated with poison dart frogs, based on samples taken from his body.
Navalny died in February 2024 at an Arctic penal colony while serving a 19-year sentence. His mother said the findings confirm long-held suspicions that he was murdered.

The Kremlin dismissed the assessment as biased and unfounded. Russian officials have consistently claimed Navalny died of natural causes, citing heart issues and other illnesses.
The Trump administration said it had no reason to dispute the European findings. Secretary of State Marco Rubio called the report troubling but said it was a European-led effort.
Navalny’s supporters marked two years since his death as pressure mounts on Russia over unanswered questions.
