The war in Ukraine entered its second year on Friday with no end in sight, a defiant President Volodymyr Zelenskiy vowing "we will defeat everyone" and global leaders set to impose new sanctions on Russia and countries supporting its war effort.

DIPLOMACY

* "This is how it began on Feb. 24, 2022," Zelenskiy said, sitting behind a desk and recalling how he addressed Ukrainians as the world reeled from Russia's act of war. "The longest day of our lives. The most difficult day in our recent history. We woke up early and haven't slept since."

* Russian Defence Minister Sergei Shoigu on Thursday accused the West of using Ukraine to try to break up Russia, but said he thought it would fail.

* The U.N. General Assembly overwhelmingly adopted a resolution on Thursday demanding that Russia pull out and stop fighting. Russia's Deputy U.N. Ambassador Dmitry Polyanskiy dismissed the action at the United Nations as "useless".

* The United States marked the anniversary invasion by announcing new sanctions against Russia and its allies, new export controls and tariffs aimed at undermining Moscow's ability to wage war. Britain imposed export bans.

* The United States plans to announce $250 million in aid on Friday to shore up Ukraine's energy infrastructure in the face of Russian attacks and $300 million for Moldova, partly to help Chisinau wean itself from energy dependence on Russia, draft documents showed.

* China called in a 12-point foreign ministry paper for a comprehensive ceasefire and a gradual de-escalation. NATO and EU offer a reserved reaction.

* U.S. Treasury Secretary Janet Yellen accused Russian officials attending a G20 finance leaders meeting of being "complicit" in atrocities, while host India avoided mentioning the war in inaugural remarks. Russia denies committing atrocities.

* Paris lit up the Eiffel Tower in blue and yellow and people draped in Ukrainian flags gathered at a vigil in London on Thursday, as the world began marking one year of war.

FIGHTING

* President Vladimir Putin said on Thursday that Russia would pay increased attention to boosting its nuclear forces by deploying a much delayed new intercontinental ballistic missile, rolling out hypersonic missiles and adding new nuclear submarines.

* Russia's Wagner group of mercenaries said on Friday it had taken full control of the Ukrainian village of Berkhivka, a village on the outskirts of Bakhmut. Ukraine's military said the armed forces fought back the attacks near the village.

* Reuters was unable to immediately confirm battlefield claims.
