Kyiv 's forces launched a “new series of battalion-sized mechanised assaults in Kursk Oblast and advanced up to five kilometres behind Russian lines southeast of Sudzha, Kursk Oblast,” the Institute for the Study of War said.

Russian invasion forces further advanced near Dachne, Zelene Pole, and Burlatske in Donetsk Oblast. In the morning briefing on Feb. 20, the General Staff stated that Ukrainian military forces halted 32 assault actions by the aggressor in the Pokrovsk sector.

Russia's army has retaken control of 64% of Kursk region territory initially captured by Ukrainian forces after they launched a surprise offensive in the border region last year, a senior Russian military official said Thursday.

Russia said its forces have taken back more than 800 square kilometers of territory from Ukraine in the Kursk region of western Russia, which had been taken by Ukraine since an incursion began last year.
