Britain and allies accuse Russia of using rare frog toxin to kill Alexei Navalny in Siberia

Britain and allies claim Russia used a rare frog toxin to kill Putin critic Alexei Navalny. Navalny died in a Siberian prison colony in 2024. Analysis of his samples allegedly revealed epibatidine, a potent neurotoxin found in South American dart frogs, which is not naturally occurring in Russia. Moscow denies the allegations, calling them propaganda. The toxin is reportedly 200 times more powerful than morphine and can cause paralysis and death.
