Ukrainian troops have apparently entered Russia’s Belgorod Oblast during the ongoing incursion into Kursk oblast, Ukrainian media reported based on a video published on the morning of Aug. 10.

In the video, posted by Ukrainian media, five uniformed men with blue tape armbands are standing outside the building as one of them says: “I wish you health, the 252nd battalion is in the village of Poroz, Belgorod Oblast. Glory to Ukraine!”

The soldiers in the video held the battalion’s flag and a Georgian flag, and the sign on the building behind them reads “Porozovsky Village Club.”

According to the Ukrainian media outlet Suspilne, the Ukrainian-based fact-checking project VoxCheck confirmed the video as filmed in Poroz, three kilometers away from the Ukrainian border.

The date of the video’s filming is unknown. It is also unknown whether it was a raid or an expansion of the ongoing cross-border incursion into Russia, Suspilne said.
