A man under arrest by Russian internal security forces was seen confessing to a “crime”, in a video posted on January 2. He had been apprehended after allegedly posting a video on social media that purportedly showed air defences near the Russian city of Belgorod. This city, on the border with Ukraine, was the target of Ukrainian missile attacks on the same day.

What was notable, though, about this confessional was that the man was flanked by two internal security officers who had the word Smersh emblazoned on the backs of their jackets.

Many people in the west remember Smersh from Ian Fleming’s early James Bond novels (and early films). It was the shadowy Soviet spy agency bent on eliminating the fictional British agent.

But there was nothing fictitious about Smersh itself. It was a real counterintelligence agency set up in Joseph Stalin’s Soviet Union during the second world war.
