As Monday draws to a close in Kyiv and in Moscow, here are the key developments of the day:
Russian troops are pushing to fully encircle the key city of Sievierodonetsk in eastern Ukraine, and Ukrainian officials say the next few days could be critical. A victory there would give Russia control of every major city of the Luhansk region, part of Ukraine's industrial eastern area of Donbas. The regional governor said Russian troops have destroyed bridges spanning a river that the Ukrainian military relied on to bring troops, arms and supplies into Sievierodonetsk.
