Ukraine's Zelenskyy defiant as Russia retreats from Kharkiv

Fresh off his country's Eurovision win, a defiant Ukrainian President Volodymyr Zelenskyy vowed early Sunday to one day host the song contest in the embattled city of Mariupol, which is almost entirely in Russian hands aside from a stalwart group of a few hundred Ukrainian fighters who continue to hold out in a steel factory.

Ukraine's Kalush Orchestra won the popular contest with its song “Stefania,” which has become a popular anthem among Ukrainians during the war, and its victory was a morale booster.

“Our courage impresses the world, our music conquers Europe,” Zelenskyy said on Facebook. “Next year, Ukraine will host Eurovision!”

The band made an impassioned plea during the show to help the fighters still in the Azovstal steel plant in the port city, and Zelenskyy said “one day” the contest would be held “in a Ukrainian Mariupol.”

The president's optimistic words come as Russian troops are retreating from Kharkiv, the country's second-largest city, after bombarding it for weeks, and Moscow's forces continue to engaged in a grinding battle for the country’s eastern industrial heartland.

Ukraine’s military said the Russian forces are now pulling back from the northeastern city to focus on guarding supply routes, while launching mortar, artillery and airstrikes in the eastern region of Donetsk in an attempt to “deplete Ukrainian forces and destroy fortifications.”

Defense Minister Oleksii Reznikov said Ukraine was “entering a new — long-term — phase of the war.”

Russian forces control a horseshoe-shaped swath of territory in the Ukrainian areas of Donetsk and Luhansk, which make up the eastern Donbas region, along the border of the industrial region where Ukraine has battled Moscow-backed separatists since 2014.

In the southern Donbas, the Azov Sea port of Mariupol is now largely in Russian control, except for the few hundred troops left in the steel factory.

A convoy of between 500 and 1,000 cars carrying civilians out of the city was reportedly able to reach the Ukrainian-held city of Zaporizhzhia on Saturday, while Ukrainian Deputy Prime Minister Iryna Vereshchuk said authorities were negotiating the evacuation of 60 severely wounded troops at the steelworks.

After failing to capture Kyiv following the Feb. 24 invasion, Russian President Vladimir Putin has shifted his focus eastward to the Donbas, aiming to encircle Ukraine's most experienced and best-equipped troops, and to seize territory still under Ukraine's control.

Airstrikes and artillery barrages make it extremely dangerous for journalists to move around in the east, hindering efforts to get a full picture of the fighting. But it appears to be a back-and-forth slog without major breakthroughs on either side.

Russia has captured some Donbas villages and towns, including Rubizhne, which had a prewar population of around 55,000.

Zelenskyy said Ukraine’s forces have also made progress in the east, retaking six towns or villages in the past day. In his nightly address Saturday, he said “the situation in Donbas remains very difficult” and Russian troops were “still trying to come out at least somewhat victorious.”

“Step by step,” Zelenskyy said, “we are forcing the occupants to leave the Ukrainian land.”

Kharkiv, which is near the Russian border and only 80 kilometers (50 miles) southwest of the Russian city of Belgorod, has undergone weeks of intense shelling. The largely Russian-speaking city with a prewar population of 1.4 million was a key military objective earlier in the war, when Moscow hoped to capture and hold major cities.

Ukraine “appears to have won the Battle of Kharkiv,” said the Institute for the Study of War, a Washington-based think tank. “Ukrainian forces prevented Russian troops from encircling, let alone seizing Kharkiv, and then expelled them from around the city, as they did to Russian forces attempting to seize Kyiv.”

Regional Gov. Oleh Sinegubov said via the Telegram messaging app that there had been no shelling attacks on Kharkiv in the past day.

He added that Ukraine launched a counteroffensive near Izyum, a city 125 kilometers (78 miles) south of Kharkiv that has been held by Russia since at least the beginning of April.

Fighting was fierce on the Siversky Donets River near the city of Severodonetsk, where Ukraine has launched counterattacks but failed to halt Russia’s advance, said Oleh Zhdanov, an independent Ukrainian military analyst.

“The fate of a large portion of the Ukrainian army is being decided — there are about 40,000 Ukrainian soldiers,” he said.

However, Russian forces suffered heavy losses in a Ukrainian attack that destroyed a pontoon bridge they were using to try to cross the same river in the town of Bilohorivka, Ukrainian and British officials said.

Britain’s defense ministry said Russia lost “significant armored maneuver elements” of at least one battalion tactical group in the attack. A Russian battalion tactical group consists of about 1,000 troops.

The ministry said the risky river crossing was a sign of “the pressure the Russian commanders are under to make progress in their operations in eastern Ukraine.”

Putin has justified the war in Ukraine by claiming it was a response to NATO’s expansion in Eastern Europe.

But the invasion has other countries along Russia’s flank worried they could be next, and in the past week the president and prime minister of Finland said they favor seeking NATO membership. Officials in Sweden are expected to announce a decision Sunday on whether to apply to join the Western military alliance.

In a phone call Saturday, Putin told Finnish President Sauli Niinisto that there are no threats to Finland’s security and joining NATO would be an “error” and “negatively affect Russian-Finnish relations.”

The Nordic nations' potential bids were thrown into question Friday when Turkish President Recep Tayyip Erdogan said his country is “not of a favorable opinion.”

U.S. Secretary of State Antony Blinken was scheduled to meet his NATO counterparts, including Turkey's foreign minister, this weekend in Germany.
