Russia’s Defense Ministry mentioned Russian troopers and Moscow-backed separatists had additionally claimed management of Metolkine, simply southeast of Sievierodonetsk. The Russian state information company Tass mentioned that many Ukrainian fighters had surrendered there, though it was not potential to confirm the assertions independently.
As the Sievierodonetsk space fell deeper into peril on Sunday, intensifying Russian assaults throughout a lot of Ukraine — together with renewed shelling close to Kharkiv in the north, strikes at Mykolaiv in the south and destruction of infrastructure in the nation’s east and central areas — made clear that the warfare might nonetheless flare up far past Donbas, the place Russia has refocused its army efforts after failing to seize Kyiv in the spring.
Ukraine faces an more and more grim and bloody battle in its east, the place Russia is utilizing long-range artillery to bombard cities and army positions.

But it’s in the Donbas, an space of rolling plains, farm fields and coal mining cities not removed from the Russian border, that Moscow has dedicated the majority of its army energy in latest weeks. The Sievierodonetsk pocket, as army officers name the world round Sievierodonetsk and Lysychansk, is about three-quarters encircled by Russian forces, leaving solely a slender hole to the west the place Ukrainian troops come and go by village roads which are typically shelled by Russia.
Russian troops have been creeping ahead to shut the hole. On Sunday in Toshkivka, which has served as an necessary a part of Ukraine’s defensive wall, they appeared to partially succeed.
Ukrainian artillery quickly engaged them in intense preventing, Mr. Haidai mentioned, and the end result was unclear.
Ukrainian battle tanks and several other Grad a number of launch rocket methods had been seen heading in the path of the village on Sunday afternoon, smoke billowing from their chassis and treads churning up backcountry roads.
