Russia's Federal Security Service (FSB) said on March 22 that its officers detained seven men in Moscow on suspicion of collaborating with the so-called Russian Volunteers' Corps (RDK) that has fought alongside Ukraine's armed forces against Russian troops. Last month, a Moscow court sentenced former actor Kirill Kanakhin, who had joined the RDK, in absentia to life in prison on a charge of high treason. In November, a Moscow court sentenced in absentia Denis Kapustin (aka Nikitin), a commander of the RDK, to life on the same charge. The RDK has claimed several attacks in Russia's Belgorod region in recent months. To see the original story by RFE/RL's North.Realities, click here.
