Russia targeted Ukraine's Black Sea regions of Odesa and Mykolaiv with airstrikes on Tuesday, hitting private property and port infrastructure along the country's southern coast, the Ukrainian military said.
The Kremlin's forces used air-launched missiles in the attack, Ukraine's Operational Command South said in a Facebook post.
In the Odesa region, a number of private buildings in coastal villages were hit and caught fire, the report said. In the Mykolaiv region, port infrastructure was targeted despite the agreement Moscow and Kyiv signed last week that was intended to allow grain shipments to resume from Ukraine's Black Sea ports.
Hours after the strikes, a Moscow-installed official in southern Ukraine said the Odesa and Mykolaiv regions would soon be "liberated" by Russian forces, just like the already occupied Kherson region further east.
"The Kherson region and the city of Kherson have been liberated forever," the region's Russia-appointed official, Kirill Stremousov, was quoted as saying by the Russian state news agency RIA Novosti.
Meanwhile, Russia's top diplomat repeated his insistence that Moscow was ready to hold talks with Ukraine on ending the war, though he once again claimed that Kyiv's Western allies oppose a deal.
"We never refused to have talks, because everybody knows that any hostilities end at the negotiating table," Russian Foreign Minister Sergey Lavrov said on Tuesday during a trip to Uganda.
He said negotiations had gone no further since a meeting between the two sides in Istanbul at the end of March.
'Not a single safe place left'
While Ukrainian officials have spoken of a possible counteroffensive in the south, the British Defense Ministry said Tuesday there was no indication a Ukrainian warship and a stockpile of anti-ship missiles were at Odesa's port, as Moscow claimed when it struck the site over the weekend.
The British ministry said Russia sees Ukraine's use of anti-ship missiles as "a key threat" that is limiting its Black Sea Fleet.
"This has significantly undermined the overall invasion plan, as Russia cannot realistically attempt an amphibious assault to seize Odesa," the military said. "Russia will continue to prioritize efforts to degrade and destroy Ukraine's anti-ship capability."
It added that "Russia's targeting processes are highly likely routinely undermined by dated intelligence, poor planning, and a top-down approach to operations."
In other military developments, Russian shelling over the previous 24 hours killed at least three civilians and wounded eight more in Ukraine, the Ukrainian president's office said Tuesday.
In the eastern Donetsk region, where the fighting has been focused in recent weeks, shelling continued along the entire front line, with the largest cities of the region, including Bakhmut, Avdiivka and Toretsk, targeted by Russian forces, the presidential office said.
Donetsk regional governor Pavlo Kyrylenko accused Russian troops of using cluster munitions and repeated his call for civilians to evacuate.
"There is not a single safe place left, everything is being shelled," Kyrylenko said in televised remarks. "But there are still evacuation routes for the civilian population."
Wagner mercenaries seize powerplant, say analysts
The Institute for the Study of War, a think tank based in Washington, reported that Moscow was using mercenaries from the shadowy Wagner Group to capture the Vuhledar Power Plant on the northern outskirts of the village of Novoluhanske village.
But Russian forces have made "limited gains" there, according to Ukraine's General Staff.
The main Russian focus for the moment is on capturing Bakhmut, which the Russian military needs to press its offensive on the main Ukrainian strongholds in Donetsk, the cities of Sloviansk and Kramatorsk.
"Russian forces made marginal gains south of Bakhmut but are unlikely to be able to effectively leverage these advances to take full control of Bakhmut itself," the Institute for the Study of War said.
Russian forces continued to launch strikes on civilian infrastructure in Kharkiv, Ukraine's second-largest city, and the surrounding region in the country's northeast.
Kharkiv Governor Oleh Syniehubov said the strikes on the city resumed around dawn Tuesday and damaged a car dealership.
"The Russians deliberately target civilian infrastructure objects — hospitals, schools, movie theaters," Syniehubov told Ukrainian television. "Everything is being fired at, even queues for humanitarian aid, so we're urging people to avoid mass gatherings."
German Foreign Minister Annalena Baerbock said that Moscow wants "the complete subjugation of Ukraine and its people."
"We must be prepared for this war — which Russia is conducting with absolute brutality and is conducting in a way that no one else would — to last months," Baerbock said during a visit to Prague.
