LONDON, Feb 14 - Five European allies on Saturday blamed Russia for killing late Kremlin critic Alexei Navalny using toxin from poison dart frogs while he was held in an Arctic penal colony two years ago, a claim Moscow rejected as propaganda.

In a joint statement, Britain, France, Germany, Sweden and the Netherlands said analyses of samples from Navalny's body "conclusively" confirmed the presence of epibatidine, a toxin found in poison dart frogs in South America and not found naturally in Russia.
