The invasion was internationally condemned; many countries imposed sanctions against Russia and increased existing sanctions. Russia abandoned an attempt to take Kyiv in early April 2022 amid fierce resistance. From August, Ukrainian forces began recapturing territories in the north-east and south as a result of counter-offensives. In late September, Russia declared the annexation of four partially-occupied regions in southern and eastern Ukraine, which was internationally unrecognized. Russia spent the winter conducting failed offensive operations in the Donbas, and in the spring of 2023 dug into positions for an anticipated Ukrainian counteroffensive.
