Zaporizhzhia (Ukraine), May 7 (AP): Fifty more civilians, including 11 children, were rescued Friday from the tunnels under a besieged steel plant in Mariupol where Ukrainian fighters have been making their last stand to prevent Moscow's complete takeover of the strategically important port city.

The Russian military said Friday that 11 children were among the 50 civilians who were evacuated from the Azovstal steel plant and handed over to representatives of the United Nations and the International Committee of the Red Cross.

Ukraine's deputy prime minister, Iryna Vereshchuk, confirmed that 50 "women, children and elderly people" managed to leave the sprawling complex, and she and Russia said evacuation efforts would continue Saturday. The new evacuees were in addition to roughly 500 civilians who the UN said were evacuated from the plant and city in recent days.

The fight for the last Ukrainian stronghold in a city reduced to ruins by the Russian onslaught appeared increasingly desperate amid growing speculation that President Vladimir Putin wants to finish the battle for Mariupol so he can present a triumph to the Russian people in time for Monday's Victory Day, the biggest patriotic holiday on the Russian calendar.

As the holiday commemorating the Soviet Union's World War II victory over Nazi Germany approached, cities across Ukraine prepared for an expected increase in Russian attacks and officials urged residents to heed air raid warnings.

"These symbolic dates are to the Russian aggressor like red to a bull," said Ukraine's first deputy interior minister, Yevhen Yenin. "While the entire civilised world remembers the victims of terrible wars on these days, the Russian Federation wants parades and is preparing to dance over bones in Mariupol." Roughly 2,000 Ukrainian fighters, by Russia's most recent estimate, are holed up in the vast maze of tunnels and bunkers beneath the Azovstal steelworks, and they have repeatedly refused to surrender. Ukrainian officials said before Friday's evacuations that a few hundred civilians were also trapped there, and fears for their safety have increased as the battle has grown fiercer in recent days.

Kateryna Prokopenko, whose husband, Denys Prokopenko, commands the Azov Regiment troops inside the plant, issued a desperate plea to also spare the fighters. She said they'd be willing to go to a third country to wait out the war but would never surrender to Russia because that would mean "filtration camps, prison, torture, and death." If nothing is done to save her husband and his men, they will "stand to the end without surrender," she told The Associated Press on Friday.

UN officials have been tightlipped about the evacuation efforts, but it seemed likely that the latest evacuees would be taken to Zaporizhzhia, a Ukrainian-controlled city about 140 miles (230 kilometers) northwest of Mariupol where others who escaped the port city were brought.

Fighters defending the plant said Friday on Telegram that Russian troops had fired on an evacuation vehicle on the plant's grounds. They said the car was moving toward civilians when it was hit by shelling, and that one soldier was killed and six were wounded.

Moscow didn't immediately acknowledge renewed fighting there Friday.

Russia took control of Mariupol, aside from the steel plant, after bombarding it for two months. Ahead of Victory Day, municipal workers and volunteers cleaned up what remains of the city, which had a prewar population of more than 4,00,000 but where perhaps 1,00,000 civilians remain with little food, water, electricity or heat. Bulldozers scooped up debris and people swept streets against a backdrop of hollowed-out buildings as workers repaired a model of a warship and Russian flags were hoisted.

The fall of Mariupol would deprive Ukraine of a vital port. It would also allow Russia to establish a land corridor to the Crimean Peninsula, which it seized from Ukraine in 2014, freeing some of its troops to fight elsewhere in the Donbas, the eastern industrial region that the Kremlin says is now its chief objective. Its capture also holds symbolic value since the city has been the scene of some of the worst suffering of the war and a surprisingly fierce resistance.

Asked whether Russia would soon take full control of Mariupol, Ukrainian President Volodymyr Zelenskyy said: "Mariupol will never fall. I'm not talking about heroism or anything." "It is already devastated," he told a meeting at London's Chatham House think tank. He also said he remains open to negotiations with Russia, but repeated that Moscow must withdraw its forces.

"We do not see the end of the war yet," he said, calling on Russia to allow safe passage out of the Mariupol steel plant to the Ukrainian troops who are there.

While they pounded away at the plant, Russian forces struggled to make significant gains elsewhere, 10 weeks into a devastating war that has killed thousands of people, forced millions to flee the country and flattened large swaths of cities.

The Ukrainian military's general staff said Friday that its forces repelled 11 attacks in the Donbas region and destroyed tanks and armoured vehicles, further frustrating Putin's ambitions after his abortive attempt to seize Kyiv. Russia gave no immediate acknowledgement of those losses. (AP) DIV DIV
