 The Russian Volunteer Corp, R.V.C., a group saying they represent armed Russian fighters opposed to the Kremlin, claimed on Monday to have captured a Russian armored personnel carrier in Kazinka, in Russia's Belgorod region. The video shows the person purported to represent the R.V.C. placing a sticker reading R.V.C. on an armored vehicle over the Z-symbol used to identify Russian forces. In a second clip, an armored vehicle was seen in a damaged building at the Gravoron border crossing, riding on a nearby wall-red greetings from Bakhmet. Fighting in Russia's Belgorod region entered a second day on Tuesday, after a cross-border incursion of armed fighters from Ukraine.
