In the last three days, the review notes, the Ukrainians have established bridgeheads on the eastern bank of the Oskol River in the Kharkiv region - although earlier the Russian forces hoped to make the river part of their new line of defense at the borders, where they retreated after the successful counteroffensive of the Armed Forces of Ukraine.

 In Donetsk region, the Armed Forces of Ukraine continue their attacks in the Lyman area, which was captured by Russian troops in May.

 "The situation on the battlefield remains difficult, but now Ukraine is putting pressure on those territories that Russia considers very important for its military goals," the review emphasizes.
