Organisation for the Prohibition of Chemical Weapons

The Organisation for the Prohibition of Chemical Weapons (OPCW) is not directly mentioned in the provided articles. The articles focus on the death of Russian opposition leader Alexei Navalny. Five European countries – the United Kingdom, France, Germany, Sweden, and the Netherlands – have accused Russia of poisoning and killing Navalny using dart frog toxin. These accusations are based on lab results from a sample taken from Navalny. The UK is considering new sanctions against Russia in response. Russia has dismissed these allegations as Western propaganda. The US was not part of the intelligence agencies making the claim. The OPCW's relevance, if any, would stem from its mandate to investigate and verify the destruction of chemical weapons and to prevent their re-emergence. If the dart frog toxin is classified as a chemical weapon, the OPCW might be involved in investigations, but the articles do not explicitly state this.
