On August 2024, the Ukrainian Armed Forces launchedan offensive operation in Russia'sKursk Oblast.[1] In March 2025, Russian forces launched a counteroffensive, resulting in the liberation of most of the territory that had come under Ukrainian control,[2][3] and entering Ukrainian territory in theSumy Oblast.[4]
The incursion near Tyotkino reportedly began in the night of 4–5 May.[5][6][7] Geolocated footage posted on 6 May indicated that Ukrainian forces had crossed the international border between Ukraine'sSumy Oblast and Russia'sKursk Oblast, advancing into the village of Tyotkino.[8] The footage depicted a Russian airstrike on a building in the southern part of the settlement. Russian sources claimed that Ukrainian forces had advanced no further than two streets into the settlement.[9]
The following day, geolocated footage indicated that Ukrainian forces had advanced further in the southwestern part of the settlement, along Chapayeva Street, as well as southeast of Tyotkino.[10] There were also reports among Russian sources that Ukrainian forces had taken control over the village ofNovyi Put.[11][12] Both Russia and Ukraine accused each other of violating the unilateral Russian ceasefire declared during theVictory Day holiday.[13] Geolocated footage posted on 10 May indicated that Ukrainian forces had advanced over an agricultural compound south of Tyotkino.[14][15]
Russian forces conducted offensive operations in Kursk Oblast on May 30 and 31. Russian sources said that Ukrainian forces attempted to attack towards Novyi Put and Tyotkino.[16] In the first week of June, the Ukrainian forces continued their attacks in the Kursk Oblast in the area of Tyotkino,Popovo-Lezhachi, Novyi Put,Vesyoloye, as well asGornal andGuyevo.[17][18] Russian forces continued conducting ground assaults in unspecified areas of Kursk Oblast on June 11 and 12. Russian sources claimed that Ukrainian forces attacked from Sumy Oblast in the Glushkovo and Tyotkino (southwest of Glushkovo) directions.[19]
According to the military blogger "Reporting from Ukraine", the incursion put extra pressure on the Russian reserves and may have forced them into an overreaction that could have led to even more serious problems such as an operational-level penetration. The blogger said the goal of the incursion was to open a fresh front, stretch Russian defenses even further, and exploit vulnerabilities, especially as Russian forces remained engaged withthe Ukrainian operations in Belgorod andthe initial Kursk assault.[20]
