Ukrainian defenses have largely stalled Russian advances in Eastern Ukraine. Russian troops conducted a number of unsuccessful attacks in Eastern Ukraine on May 4 and were unable to make any confirmed advances. Russian forces attacking south of Izyum appear increasingly unlikely to successfully encircle Ukrainian forces in the Rubizhne area. Ukrainian forces have so far prevented Russian forces from merging their offensives to the southeast of Izyum and the west of Lyman, Slovyansk, and Kramatorsk, as Russian forces likely intended.
Russian forces reportedly entered the Azovstal Steel Plant – rather than its outskirts – for the first time on May 4. The extent of this Russian advance remains unclear, and Russian forces likely face further costly fighting if they intend to clear the entire facility. The Kremlin likely hopes that the successful capture of Azovstal through a ground assault will cement the Kremlin’s growing effort to claim complete control of Mariupol by May 9, with Russian propagandists recently arriving in the city to set conditions for further claims of a Russian victory. The Kremlin likely intends to claim some sort of victory in Mariupol to present a success to the Russian people, though Russian forces are highly unlikely to halt offensive operations across Ukraine on this date.
Russian forces intensified airstrikes against transportation infrastructure in Western Ukraine on May 4 but remain unable to interdict Western aid shipments to Ukraine. Six Russian cruise missiles hit electrical substations near railway stations in Lviv and Transcarpathia (the southwestern Oblast of Ukraine) on May 4. A senior US defense official reported that Russian aircraft conducted 200 to 300 airstrikes largely targeting transportation infrastructure in the last 24 hours. The US official added that these Russian strikes are likely intended disrupt Ukrainian transportation capabilities and slow down weapon re-supply efforts but have been unable to do so.
