Russia killed Alexei Navalny with frog toxin, UK and four European allies say
Epibatidine, the dart frog toxin Britain says was used to kill Alexei Navalny, is about 100 times more potent than morphine.
The extremely toxic, nicotine-like substance was first derived from the Epipedobates genus of poison dart frogs native to northern South America – which are not found naturally in Russia.
Frogs that secrete the toxin on to their skin include the brightly coloured Anthony’s poison arrow frog and the Phantasmal poison frog.
