Russian troops are withdrawing from around Ukraine’s second-largest city after bombarding it for weeks, the Ukrainian military said as Kyiv and Moscow’s forces engaged in a grinding battle for the country’s eastern industrial heartland.
Ukraine’s general staff said the Russians were pulling back from around the north-eastern city of Kharkiv and focusing on guarding supply routes, while launching mortar, artillery and air strikes in the eastern Donetsk province in order to “deplete Ukrainian forces and destroy fortifications”.
Defence minister Oleksii Reznikov said Ukraine was “entering a new – long-term – phase of the war”.
President Volodymyr Zelensky said Ukrainians were doing their “maximum” to drive out the invaders and that the outcome of the war would depend on support from Europe and other allies.
“No one today can predict how long this war will last,” Mr Zelensky said in his nightly video address on Friday.
A video posted on Mr Zelensky’s Telegram account showed Mr McConnell, who represents the state of Kentucky, and senators Susan Collins of Maine, John Barrasso of Wyoming and John Cornyn of Texas greeting him.
After Russian forces failed to capture Kyiv following the February 24 invasion, President Vladimir Putin shifted his focus eastward to the Donbas, an industrial region where Ukrainian troops have battled Moscow-backed separatists since 2014.
Mr Zelensky said Ukraine’s forces had also made progress in the east, retaking six Ukrainian towns or villages in the past day.
Kharkiv, which is not far from the Russian border and only 50 miles south-west of the Russian city of Belgorod, has undergone weeks of intense shelling.
The largely Russian-speaking city with a pre-war population of 1.4 million was a key Russian military objective earlier in the war, when Moscow hoped to capture and hold major Ukrainian cities.
Regional governor Oleh Sinegubov said in a post on the Telegram messaging app that there had been no shelling attacks on Kharkiv in the past day.
He said Ukraine had launched a counteroffensive near Izyum, a city 78 miles south of Kharkiv that has been under effective Russian control since at least the beginning of April.
“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 — the largest in eastern Ukraine — in the town of Bilohorivka, Ukrainian and British officials said.
The UK Ministry of Defence said Russia lost “significant armoured manoeuvre 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”.
Mr Zelensky said in his nightly video address to the nation that Ukrainians were doing everything they could to drive out the Russians, but “no one today can predict how long this war will last”.
“This will depend, unfortunately, not only on our people, who are already giving their maximum,” he said. “This will depend on our partners, on European countries, on the entire free world.”
The Ukrainian leader warned that the war causing a food crisis around the world as a Russian blockade stops Ukrainian grain from leaving port.
The Group of Seven leading economies echoed that warning, saying on Saturday that “Russia’s war of aggression has generated one of the most severe food and energy crises in recent history, which now threatens those most vulnerable across the globe”.
This week, the president and prime minister of Finland said they favoured their country seeking Nato membership. Officials in Sweden are expected to announce a decision on Sunday on whether to apply to join the Western military alliance.
Mr Putin told Finnish President Sauli Niinisto that there are no threats to Finland’s security and joining Nato would be an “error” that would “negatively affect Russian-Finnish relations”.
The Kremlin said the two leaders had a “frank exchange of views” in a phone call on Saturday.
Mr Niinisto said the discussion “was straightforward and unambiguous and was held without exaggeration. Avoiding tensions was considered important”.
Russia’s response to the moves by Finland and Sweden has so far been muted, though deputy foreign minister Alexander Grushko said on Saturday that their accession to Nato would heighten security tensions in the Arctic, “turning it into an arena of military competition”.
Russian energy group Inter RAO on Saturday also suspended deliveries of electricity to Finland, according to a statement from the Finnish national electrical grid operator. But only around 10% of Finland’s electricity is supplied from Russia, and Finnish authorities did not expect electricity shortages.
The Nordic nations’ potential bids were thrown into question on Friday when Turkish President Recep Tayyip Erdogan said his country is “not of a favourable opinion” toward the idea.
US Secretary of State Antony Blinken is scheduled to meet his Nato counterparts, including the Turkish foreign minister, this weekend in Germany.
