How epibatidine was used in Navalny’s killing and what it means for international law

Independent testing linked Alexey Navalny’s death to epibatidine, a potent frog-derived neurotoxin; a former OPCW laboratory chief explains the science, possible motives, and the limits of international enforcement

FLASH — In the past few hours, independent European laboratories have detected traces of epibatidine in biological samples linked to Alexey Navalny. Investigators say the findings fit the profile of a deliberate poisoning.

Who: Alexey Navalny.
What: Multiple forensic teams found molecular evidence of epibatidine, a potent neuroactive alkaloid.
Where: Samples were analyzed by five separate labs across Europe.
Why it matters: The chemical fingerprint, alongside the clinical picture, points to intentional exposure and raises urgent questions about who ordered it and what legal steps will follow.

What the tests showed
All five labs reported matching results: low-level traces of epibatidine and additional molecular markers consistent with contact or ingestion of that compound. Clinicians and toxicologists reviewing the data noted a pattern of symptoms and biochemical changes that align with known effects of epibatidine exposure, strengthening the case that this was not an accidental or natural event.
