After week-long Russian strikes battered Ukraine's already failing electricity grid, causing blackouts across the war-torn nation, President Volodymyr Zelensky urged the UN to take strict action against Russia. He accused Moscow of 'crimes against humanity' in a video message to the UN Security Council meeting late Wednesday via a video link. The U.S. too accused Putin of 'weaponizing winter' to inflict suffering on Ukrainians. Meanwhile, Russia defended the strikes as an attempt to stop the flow of weapons to Kyiv from the U.S. and its allies. Watch this video for the faceoff.
