More than 250 Ukrainian fighters surrendered to Russian forces at the Azovstal steelworks in Mariupol after weeks of desperate resistance, bringing an end to the most devastating siege of Russia's war in Ukraine and allowing President Putin to claim a rare victory in the campaign. FIGHTING, CIVILIANS

* Russia's defence ministry said 265 fighters had surrendered at the Azovstal steelworks, including 51 who were seriously wounded and would be treated at Novoazovsk in the Russian-backed breakaway Donetsk region. * The defenders of Mariupol changed the course of the war with Russia by holding out for 82 days, Ukrainian presidential adviser Mykhailo Podolyak said, adding that they had interrupted Russia's operation to seize swathes of territory in eastern and southern Ukraine.

* Russian attacks killed seven civilians in the Donetsk region, the area's governor said on his Telegram channel. Reuters could not independently confirm the governor's account. * Eight people were killed and 12 wounded in a Russian air strike on the village of Desna in the northern Ukrainian region of Chernihiv, the regional emergency service said.

* A village in Russia's western province of Kursk bordering Ukraine came under Ukrainian fire, the regional governor said, but there were no injuries. DIPLOMACY

* Peace negotiations between Russia and Ukraine have stagnated, officials said, with both sides trading blame and Moscow indicating a return to talks may be difficult. * Russian Foreign Minister Lavrov said that Finland and Sweden joining NATO would probably make "not much difference" as the two countries had long participated in the alliance's military drills.

ECONOMY * Russia's largest lender Sberbank, which has been hit by Western sanctions, plans to drop its listing in London after its depositary terminated an agreement with it, the bank said.

* German Finance Minister Christian Lindner said he was open to the idea of seizing Russian state assets to finance the reconstruction of Ukraine. * The European Commission said opening accounts in roubles at a Russian bank to pay for gas would breach the bloc's sanctions against Moscow.

* U.S. Treasury officials plan to propose at this week's G7 finance meeting that European countries impose tariffs on Russian oil. (Compiled by Nick Macfie, Frank Jack Daniel; editing by Grant McCool)
