evidence: On 30 September 2022, Russia, amid an ongoing invasion of Ukraine, unilaterally declared its annexation of areas in and around four Ukrainian oblasts—Donetsk, Kherson, Luhansk and Zaporizhzhia. Most of Luhansk Oblast and part of Donetsk Oblast had been controlled by pro-Russian separatists since 2014, while the Kherson and Zaporizhzhia Oblasts were invaded by Russia in 2022. The boundaries of the areas to be annexed and their borders were not defined; Russian officials stated that they would be defined later. None of the oblasts were fully under Russian control at the time of the declaration, nor since. If limited to the areas then under Russian control (about 90,000 km2 or 15% of Ukraine's territory, roughly the size of Portugal) the annexation would still be the largest in Europe since World War II.[5] [...] Even Mr Peskov was unable to define where Russia would draw its new borders in occupied southern Ukraine. However, he said Russia would treat all of the Donetsk region as part of Russia. As for those parts not under occupation, he said those would have to be "liberated".
