In an effort to counter Ukraine's 2024 offensive in Kursk, in early 2025 Russian forces launched cross-border incursions from Russia into Ukraine's adjacent Sumy Oblast.

On 10 January 2025, Russian troops crossed the international border into Ukraine's Sumy Oblast, advancing west of Zhuravka. However, a few days later, the Ukrainian military claimed their forces had successfully pushed back the Russian attack.

In mid-February, Russian forces launched another cross-border incursion, claiming to have entered the villages of Novenke and Basivka. The former village was captured within a few days.

By the end of February, Ukraine's Center for Combatting Disinformation acknowledged the presence of Russian forces, while DeepState described Basivka and Novenke as "gray zones."
