The founder of Russia's opposition Yabloko party, which wants a ceasefire in Ukraine, has said his party will keep campaigning despite the arrest of two senior figures, a move he said was meant to derail it before next year's parliamentary election.

Ukrainian President Volodymyr Zelenskyy said in a social media post on Sunday morning that "hundreds of thousands" of Ukrainians were without electricity across multiple regions following Russian missile and drone attacks on the country's energy infrastructure.

A senior Kremlin official says Russian police and the National Guard will stay on in eastern Ukraine’s Donbas even if a peace settlement ends the war.

EU leaders are under pressure to hammer out how to keep financing Ukraine at a summit starting Thursday -- with key player Belgium resisting a push to use frozen Russian assets. EU officials have promised leaders will not leave the summit until they agree how to keep funding Ukraine -- setting up potentially marathon talks in Brussels.

Ukraine's southern port city of Odesa and the surrounding region suffered major blackouts on Saturday after a large overnight Russian attack on the power grid that left more than a million households without power.

Much of Ukraine’s largest Black Sea port was without power, heat and water on Saturday after strikes from Russia, which has shown little appetite for a deal to end the war.

Volodymyr Zelenskyy claimed that the latest wave of attack are a clear indication that Moscow does not intend to end the Russia-Ukraine war.
