Russia appeared to make a breakthrough in Ukraine's eastern region of Donetsk, as its forces were reported to be rapidly infiltrating positions north of Pokrovsk.

Ukraine's military said its forces are fending off Russian infantry units trying to infiltrate their defensive positions in the Donetsk region.

The region's Ukrainian military command posted on Facebook Monday that Russian soldiers penetrating Ukrainian lines to capture more territory "face inevitable death” but acknowledges that the situation remains “difficult, unpleasant and dynamic.”

Serhii Filimonov, the commander of the Da Vinci Wolfs 108 Separate Battalion, which is fighting in the Pokrovsk direction, says Russia wants to cut the logistic roads.

They used the same tactics in other towns. 

"If they capture Pokrovsk, then in the future they will cut off logistics, logistics in Druzhkivka, Kramatorsk, Sloviansk and Kostyantynivka will be significantly complicated. I think that Kostyantynivka can fall without a fight if they manage to do it", said Filimonov.

At night, medics of the medical service "Ulf" of Da Vinci Wolfs 108 Separate Battalion treated soldiers with burned faces and hands, after they were attacked by Russian FPV drones.
