Kyiv — Russia confirmed on Thursday it will formally
Peskov said the pro-Moscow administrators of the regions will sign treaties to join Russia during the ceremony at the Kremlin's St. George's Hall.
The official annexation was widely expected following the votes that wrapped up on Tuesday in the areas under Russian occupation in Ukraine and after Moscow claimed residents overwhelmingly supported for their areas to formally become part of Russia.
The United States and its Western allies have sharply condemned the votes as "sham referenda" and vowed never to recognize their results. German Foreign Minister Annalena Baerbock on Thursday joined other Western officials in denouncing the referendums.
"Under threats and sometimes even (at) gunpoint people are being taken out of their homes or workplaces to vote in glass ballot boxes," she said at a conference in Berlin.
"This is the opposite of free and fair elections," Baerbock said. "And this is the opposite of peace. It's dictated peace. As long as this Russian diktat prevails in the occupied territories of Ukraine, no citizen is safe. No citizen is free."
United Nations Secretary-General Antonio Guterres issued a statement condemning the Russian plan.
"The UN Charter is clear," he said. "Any annexation of a State's territory by another State resulting from the threat or use of force is a violation of the Principles of the UN Charter and international law."
"I must be clear," stressed Guterres. "The Russian Federation, as one of the five permanent members of the Security Council, shares a particular responsibility to respect the Charter. Any decision to proceed with the annexation of Donetsk, Luhansk, Kherson and Zaporizhzhia regions of Ukraine would have no legal value and deserves to be condemned. It cannot be reconciled with the international legal framework."
Armed troops had gone door-to-door with election officials to collect ballots in five days of voting. The suspiciously high margins in favor were characterized as a land grab by an increasingly cornered Russian leadership after embarrassing military losses in Ukraine.
Moscow-installed administrations in the four regions of southern and eastern Ukraine claimed Tuesday night that 93% of the ballots cast in the Zaporizhzhia region supported annexation, as did 87% in the Kherson region, 98% in the Luhansk region and 99% in Donetsk.
Ukraine too , saying it has every right to retake the territories, a position that has won support from Washington.
The Kremlin has been unmoved by the criticism. After a counteroffensive by Ukraine this month dealt Moscow's forces heavy battlefield setbacks, Russia said it would call up 300,000 reservists to join the fight. It also if its territory is attacked — and many have viewed the looming annexations as a way for Putin to create the pretext of exactly such a direct attack on Russia.
Also on Thursday, Ukrainian authorities said Russian shelling has killed at least eight civilians, including a child, and wounded scores of others. A 12-year-old girl has been pulled out of rubble after an attack on Dnipro, officials said.
"The rescuers have taken her from under the rubble, she was asleep when the Russian missile hit," said local administrator Valentyn Reznichenko.
Reports of new shelling came as Russia appeared to continue to lose ground around a key northeastern city of Lyman while it struggles to press on with chaotic mobilization of troops and prevent the fighting-age men from leaving the country, according to a Washington-based think-tank and the British intelligence reports.
The Institute for the Study of War, citing Russian reports, said Ukrainian forces have taken more villages around Lyman, a city some 100 miles southeast of Kharkiv, Ukraine's second-largest city. The report said Ukrainian forces may soon encircle Lyman entirely, in what would be a major blow to Moscow's war effort.
"The collapse of the Lyman pocket will likely be highly consequential to the Russian grouping in northern Donetsk and western Luhansk oblasts and may allow Ukrainian troops to threaten Russian positions along the western Luhansk" region, the institute said.
The British military intelligence report claimed the number of Russian military-age men fleeing the country likely exceeds the number of forces Moscow used to initially invade Ukraine in February.
"The better off and well educated are over-represented amongst those attempting to leave Russia," the British said. "When combined with those reservists who are being mobilized, the domestic economic impact of reduced availability of labor and the acceleration of 'brain drain' is likely to become increasingly significant."
That partial mobilization is deeply unpopular in some areas, however, triggering protests, scattered violence, and Russians fleeing the country by the tens of thousands. Miles-long lines formed at some borders and Moscow also reportedly set up draft offices at borders to intercept some of those trying to leave.
