Russia’s Federal Security Service (FSB) announced Wednesday the detention of a Russian citizen allegedly planning to set fire to a military enlistment office. The FSB claims the individual was acting on instructions from Ukraine. The intended target was a facility in the Kaluga Region of Russia. This alleged plot represents a further escalation of tensions between the two countries. Russian authorities have accused Ukraine of conducting sabotage and espionage operations within its borders. The FSB did not release details regarding the evidence supporting their claim, or the identity of the detained individual. This incident is likely to fuel further distrust and accusations between Russia and Ukraine.
