Moscow-held regions of Ukraine begin voting Friday on whether to become part of Russia, in referendums that Kyiv and its allies have condemned as an unlawful land grab.
The referendums in eastern Donetsk and Lugansk regions, as well as in the southern Kherson and Zaporizhzhia regions have been roundly dismissed as a sham by Kyiv's Western allies, AFP said.
They come after Putin announced this week a mandatory troop call-up for about 300,000 reservists, which also sparked resounding condemnation in the West.
The mobilization comes after Ukrainian forces seized back most of the northeastern Kharkiv region in a huge counter-offensive that has seen Kyiv retaking hundreds of towns and villages under Russian control for months.
The four regions' integration into Russia -- which for most observers is already a foregone conclusion -- would represent a major new escalation of the conflict.
"We cannot –- we will not -– allow President Putin to get away with it," US Secretary of State Antony Blinken said in a UN Security Council session on Thursday, lashing out against the referendums as a "sham".
"The very international order we've gathered here to uphold is being shredded before our eyes... (Defending Ukraine's sovereignty) is about protecting an international order where no nation can redraw the borders of another by force," he said.
The referendums are reminiscent of a similar sort in 2014 that saw the Crimean Peninsula in Ukraine annexed by Russia.
Western capitals have maintained that the vote was fraudulent and hit Moscow with sanctions in response.
In New York this week, Western leaders have unanimously condemned the ballots and the troop call-up, with French President Macron telling the UN General Assembly that the referendums were a "travesty".
Russian Foreign Minister Sergei Lavrov lashed out at the accusations, condemning Ukraine for driving "Russophobia".
"There's an attempt today to impose on us a completely different narrative about Russian aggression as the origin of this tragedy," Lavrov told the Security Council.
- 'A farce' -
In the eastern Donetsk and Lugansk regions -- already recognized as independent by Putin right before he launched the invasion in February -- residents will have to answer if they support their "republic's entry into Russia", according to Russian news agency TASS.
Ballots in Kherson and Zaporizhzhia regions will have this question: "Are you in favor of secession from Ukraine, formation of an independent state by the region and its joining the Russian Federation as a subject of the Russian Federation?"
And the voting process in the four regions would be untraditional, TASS said.
"Given the short deadlines and the lack of technical equipment, it was decided not to hold electronic voting and use the traditional paper ballots," it added.
Instead, authorities would go door-to-door for the first four days to collect votes, and then polling stations would be open on the final day, Tuesday, for residents to cast ballots.
Leonid Pasechnik, the leader of self-proclaimed Lugansk People's Republic, told TASS they have been waiting for this referendum since 2014, calling it "our common dream and common future".
But Ukrainian President Volodymyr Zelensky denounced the referendums as a "farce", and hailed Western allies for their condemnation of Russia's moves.
"I am grateful to everyone in the world who supported us, who clearly condemned another Russian lie," he said during his daily address on Thursday.
Putin said Moscow would use "all means" to protect its territory -- a statement that former Russian leader Dmitry Medvedev said on social media would mean including "strategic nuclear weapons".
Medvedev also predicted the voting regions "will integrate into Russia".
- Russians fleeing -
Moscow on Thursday began its mandatory troop call-up, after Putin's call for about 300,000 reservists to bolster the war effort.
Amateur footage posted on social media purported to show hundreds of Russian citizens across the country responding to the military summons, and the Russian military said that at least 10,000 people had volunteered to fight in 24 hours since the order.
But men were also leaving Russia in droves before they were made to join, and across Russia on Wednesday, more than 1,300 people were arrested during protests, a monitoring group reported.
Flights to neighboring countries, mainly former Soviet republics that allow Russians visa-free entry, are nearly entirely booked and prices have skyrocketed, pointing to an exodus of Russians wanting to avoid going to war.
"I don't want to go to the war," a man named Dmitri, who had flown to Armenia with just one small bag, told AFP.
"I don't want to die in this senseless war. This is a fratricidal war."
Military-aged men made up the majority of those arriving off the latest flight from Moscow at Yerevan airport and many were reluctant to speak.
The Armenian capital has become a major destination for Russians fleeing since war began on February 24, drawing fierce international opposition that has aimed to isolate Russia.
Looking lost and exhausted in Yerevan airport's arrivals hall, 44-year-old Sergei said he had fled Russia to escape being called up.
"The situation in Russia would make anyone want to leave," he told AFP.
Calling on Russians to resist the mobilization, Zelensky urged them to protest, fight back "or surrender" to the Ukrainian army.
"You are already complicit in all these crimes, murders and torture of Ukrainians. Because you were silent," he said.
