 Drone footage released on May 22 showed plumes of smoke rising in Russia's Belgorod region as the local governor said Ukrainian saboteurs had burst through the front line from Ukraine. In the short video clip, smoke could be seen rising above fields and buildings in the small town of Ksenia near the border with Ukraine. The governor of Russia's Belgorod region said a Ukrainian sabotage group had entered Russian territory in the nearby Gravoron district and was being repelled. But the Ukrainian outlet Romatsk cited Ukrainian military intelligence as saying two armed Russian opposition groups, the Liberty of Russia Legion and the Russian Volunteer Corps, both consisting of Russian citizens, had carried out the attack.
