The frontline remains highly fluid as Ukrainian forces carry out small counterattacks while using drones to disrupt Russian logistics up to 20km behind the lines. Russia is pressing attacks on fortified cities in Donetsk, including Dobropillia, Vovchansk, and Kostiantynivka, where fighting is increasingly inside the city. Moscow is also advancing in Sumy and Kharkiv regions, aiming to create a buffer zone and stretch Ukrainian defenses.
