LONDON, Nov 13 (Reuters) - A video purportedly showing the sledgehammer execution of a former Russian mercenary who switched sides to back Ukraine was circulated on Russian social media on Sunday, with pro-Russian bloggers saying it was revenge for his alleged treachery.
In an unverified video distributed on Telegram channels which Russian media said were linked to the Wagner mercenary group, the man identified himself as Yevgenny Nuzhin, 55, and said he had changed sides to "fight against the Russians".
Wagner group, originally staffed by veterans of the Russian armed forces, has fought in Libya, Syria, the Central African Republic, Mali and Ukraine, among other countries.
Wagner has been recruiting convicts in Russian jails in recent months, according to a video which showed Yevgeny Prigozhin, the founder of the Wagner mercenary group, speaking to convicts in a Russian jail.
Asked to comment on the execution video, Prigozhin, the founder of the Wagner mercenary group, said in remarks released by his spokeswoman that the video should be called "A dog receives a dog's death."
