The Ukrainian military says Russia has been beefing up its forces and trying to probe Ukrainian defenses, per the AP. The Ukrainian military command said Sunday that the Russian troops have continued attempts to break Ukrainian defenses near Izyum, southeast of Kharkiv. The military added that the Russians also continued their attempts to take control of Mariupol, the Sea of Azov port that has been besieged by Russian forces for nearly 1½ months. After Russia’s attempt to capture Kyiv and other big cities in northeastern Ukraine failed, Ukrainian and Western officials expect Moscow to launch a new offensive in eastern Ukraine. Developments:
