Ukrainian President Volodymyr Zelenskyy, in his New Year address to the nation, said late on Wednesday that Kyiv wanted the war to end, but not at any cost, adding he would not sign a "weak" peace agreement that would only prolong the war.

The Kremlin said on Tuesday its position would toughen in talks on ending the war in Ukraine after accusing Kyiv of attacking a Russian presidential residence, an allegation that Kyiv said was baseless and intended to prolong the conflict.

Russian commanders told Putin during an inspection visit that Moscow's forces had captured towns in Ukraine's eastern region of Donetsk.

Ukrainian long-range drones struck the Temp oil depot in the Russian city of Rybinsk, an official from Kyiv's SBU domestic security service says. Officials said the attack on the facility, which the SBU said was a key logistics hub for fuel, sparked a large fire.

Russia has carried out some of the heaviest attacks on Kyiv in months, using an estimated 500 drones and 40 missiles, said Ukrainian President Volodymyr Zelenskyy.

The virtual meeting included European leaders as well as Canadian Prime Minister Mark Carney, heads of European institutions and NATO Secretary-General Mark Rutte.

Before the attacks, Zelenskiy said his talks in Florida on Sunday would focus on the territory to be controlled by each side after a halt to the fighting that began in February 2022.
