This is a special issue of the Rondeli Russian Military Digest dedicated to the Russo-Ukrainian War, composed on the basis of numerous open sources.
Russians engaged in unsuccessful attempts to attack to the south of Izyum.
They achieved new limited advance in the north of Donbas area, taking the village of Zelena Dolyna and trying to attack from there southward in the direction of the town of Lyman. Northeast of Lyman, fighting continued in the town of Zarichne which appeared to still be contested as of the afternoon 25 April (in Special Issue 18 of this digest covering 18-20 April we said that Zarichne had “likely” been taken by Russians).
Street fighting continued within Rubizhne and Popasna.
Russians achieved progress in the area between Popasna and Severodonetsk, taking the town of Novotoshkivske and advancing a little to the west of it.
Russians were not able to achieve progress on the portion of the frontline to the west of Donestk and Horlivka, including in the areas of Mar’inka and Avdiivka.
In the south of Donbas, Russians managed to advance about 10 kilometers in the northwestern direction in the area between Temyrivka and Velyka Novosilka.
