Russia bombed Lviv and its missiles struck Kyiv and Kharkiv on Saturday, as Moscow followed through on a threat to launch more long-range attacks on Ukrainian cities.
In besieged Mariupol, scene of the war's heaviest fighting and worst humanitarian catastrophe, Russian troops pressed recent advances, hoping to make up for their disappointment to capture Kyiv by seizing their first big prize of the war.
There are reports that Mariupol will be completely sealed for entry and exit from Monday, potentially locking the city and stopping further humanitarian evacuations.
Deputy Mayor Serhii Orlov said he believes Russian forces plan to implement “more strict” rules within the city involving checkpoints to monitor and restrict movement between districts.
Russia banned British Prime Minister Boris Johnson and 12 other politicians from entering Russia this afternoon over their “hostile” stance on the conflict.
Russia's foreign ministry said Foreign Secretary Liz Truss, former prime minister Theresa May and First Minister of Scotland Nicola Sturgeon were among 13 British government members and politicians barred from entering the country.
Russia has warned that further shipments of Western military equipment to Ukraine could result in “unpredictable consequences”.
Ukraine's President Volodymyr Zelenskiy said about 2,500-3,000 Ukrainian troops have been killed so far, compared to up to 20,000 Russian troops.
Moscow has given no updates on its military casualties since March 25, when it said 1,351 had died. Western estimates of Russian losses are many times higher, while there are few independent estimates of Ukraine's losses.
Ukraine says civilian deaths are impossible to count, estimating tens of thousands have been killed in Mariupol alone.
The UN says 4,633 civilian casualties have now been officially recorded in Ukraine since the start of the war, but added that the number is likely to be far higher.
Andriy Nebytov, head of the region’s police force, said more bodies are being found every day under rubble and in mass graves, with the largest number found in Bucha, more than 350.
