Key event

Armed raid into Belgorod region

22 – 23 May 2023 Belgorod region (RU)

What happened

Armed formations of Russian citizens fighting on Ukraine's side — the Freedom of Russia Legion and the Russian Volunteer Corps, by their own and Kyiv's account — cross into Belgorod region and hold border settlements for roughly two days before withdrawing. Kyiv describes the raid as an operation of Russian formations acting independently of its army.

Militarily small, politically loud: the first sustained ground fighting inside Russia since the invasion began forced border-defence attention and made the anti-Kremlin Russian formations a public factor — while every detail of composition and control stayed contested information-war ground.

Confidence: Moderate
