Latest Developments in Ukraine: May 18 by VOA News For full coverage of the crisis in Ukraine, visit [1]Flashpoint Ukraine. The latest developments in the conflict between Russia and Ukraine. All times EDT: 1:15 a.m.: Lawmakers in Finland voted overwhelmingly Wednesday in favor of the country joining NATO by a vote of 188-12, marking a dramatic reversal of Finland's military non-alignment policy dating back more than 75 years. Agence France-Presse has the video: 12:30 a.m.: The fall of the Ukrainian port of Mariupol to Russia appeared imminent Tuesday as Ukraine moved to abandon the city's sprawling steel plant, and hundreds of Kyiv fighters who had been holed up there turned themselves over to Russian forces in a deal reached by the warring parties. The capture of Mariupol, a prewar city of 430,000 people along the north coast of the Sea of Azov, would be Moscow's biggest success in its nearly three-month offensive against Ukraine. But Russia is struggling to capture more territory in eastern Ukraine and has failed to topple the government of President Volodymyr Zelenskyy or take the capital, Kyiv. VOA's National Security Correspondent Jeff Seldin reports. Under constant Russian shelling, which Ukraine estimates has killed 20,000 civilians in Mariupol, much of the city has been reduced to rubble. What's left of it is situated between the Russian mainland and the Crimean Peninsula, which Russia seized from Ukraine in 2014. More than 260 Ukrainian fighters -- some of them seriously wounded and lying on stretchers -- left the ruins of the Azovstal steel plant on Monday and turned themselves over to Russian forces. Ukrainian authorities said they were working to remove its remaining soldiers from the steel mill, but it was not clear how many remained. Russia called the operation a mass surrender. The Ukrainians, in contrast, said its garrison had completed its mission. 12:01 a.m.: In an interview with VOA's Ukranian Service Tuesday, Mariupol Mayor Vadym Boychenko spoke of the courage of Ukrainian forces who defended the once-thriving Southeastern seaport besieged by Russian artillery for 82 days. "There is still a Ukrainian flag over Mariupol. And they were doing it against the powers that were [a] dozen times stronger. They were working professionally, almost without food or water. Without [much] weapons," Boychenko said. He praised Denys Prokopenko, commander of Azov special regiment, who was in charge of the defense and others who supported Ukraine's fight against Russia's invasion. "They were not only holding Mariupol, but they've held back an immense power of 20-30 professional Russian military," said Boychenko. "It has allowed the other [Ukrainian] military groups, other cities to better prepare for this war." Some information in this report came from Agence France-Presse.
