Putin is expected to annex parts of Ukraine after referendums end on Tuesday.

KYIV, Ukraine — Four days of staged referendums to join Russia in occupied parts of Ukraine concluded Tuesday, as pro-Moscow officials used crude intimidation tactics, including armed men in ski masks at polling stations, Orwellian messages and little assistance. holidays to influence the vote.

The referendums were intended as a show of democracy on Russia’s part, and while most Western leaders dismissed them as a sham, they are likely to have chilling consequences. The purported results claimed that the vast majority of residents had voted to join Russia, giving the Kremlin justification to formally announce annexation as soon as this week.

Russian state media reported what they described as results showing huge levels of support for joining Russia in four occupied territories. Tass, the Russian news agency, reported 92.68 percent in favor in Zaporizhzhia, 86 percent in Kherson in the south, 93.95 percent in Donetsk and 98.53 in Luhansk in the east.

Ukrainian President Volodymyr Zelensky told the UN Security Council that Russia was organizing “fake” referendums that were an effort to “erase the norms of international law.”

“This is an attempt to steal another state’s territory,” he said in a remote address to the Council on Tuesday.

The staged vote drew widespread international condemnation, with world leaders vowing not to recognize the announced results.

At a news conference in Washington on Tuesday, Secretary of State Anthony J. Blinken said the United States would never recognize annexed territories through referendums. He denounced Russia for what he called an “evil scheme” to drive local Ukrainian residents out of captured areas and move Russians to vote.

Dmytro Orlov, mayor of the occupied city of Melitopol, said in an interview that the results of the vote were meaningless due to intimidation tactics. “They bang hard, they ring the bell, they give people a ticket and they point with their rifles where to put the mark,” he said.

Mr. Orlov said Moscow’s goal was clear: to claim the land in four provinces partially occupied by the Russian military as Russian and to claim that Ukraine is now attacking Russia, not the other way around.

President Vladimir V. Putin has said that Russia will defend the territories by all means. The country has the largest nuclear arsenal in the world. Dmitry Medvedev, the former president of Russia who now serves as deputy chairman of the country’s Security Council, reiterated on Telegram on Tuesday that Moscow had the right to defend itself with nuclear weapons and that it was “definitely not a hoax.”

Formal annexation would require a vote in the Russian Parliament. Putin is scheduled to address both chambers on Friday, suggesting a possible vote on annexation could then take place, British military intelligence said.

Ukrainians have expressed fear that an immediate consequence of annexation will be the recruitment of their citizens into the Russian army, forcing them to take up arms against their own country. In parts of Luhansk and Donetsk, which have been occupied by Russia since 2014, that is already the case.
