- Fighting stayed intense on Sunday with 234 clashes reported by morning and the Pokrovsk axis listed as the most active, while Ukrainian forces also noted frequent attacks near the Huliaipole sector.
- Regional officials reported fresh civilian harm from Russian strikes, with injuries in Sumy and Kharkiv, a teenager among eight hurt in Kherson earlier on Saturday, and two people killed in Dnipropetrovsk region on Sunday.
