Russian forces lost almost 1,400 fighters and 50 artillery systems in the past day as the Kremlin pushes forward to threaten a key Ukrainian city in the country's eastern Donetsk region and Kyiv holds its grip on swathes of Russia's southern Kursk region. Moscow sustained 1,380 casualties between Monday and Tuesday bringing the tally of total Russian casualties to 627,790. Updated figures on Tuesday put Russia's artillery losses at 50 over the past day—with a total of 17,880 systems lost during Russia's full-scale invasion of the country, which began in February 2022.
