And in his nightly address to his nation, President Volodymyr Zelenskyy said the “advance of our forces” continues. His claims appear to be supported by the renowned think tank, the Institute for the Study of War (ISW), a US-based group that provides defense and foreign affairs research and analysis. He said the Ukrainian counteroffensive in the Kharkiv region was “displacing Russian forces and collapsing the northern axis of Russia’s Donbas.” He continued: “Russian forces are not conducting a controlled withdrawal and are hastily leaving the southeastern Kharkiv region (an administrative region) to escape the encirclement around Izyum.” A spokesman for Ukraine’s military intelligence service said Russian troops were surrendering en masse as they “realized the hopelessness of their situation” and an adviser to President Zelensky said there were so many prisoners of war the country was running out of space to house them. It is claimed that the Ukrainian army liberated more than 20 settlements within 24 hours.

He said he was grateful for the soldiers who “advanced very bravely, with great confidence” and who “advanced steadily in spite of everything – in spite of the features of the open ground, in spite of the artillery of the conquerors. “Guys, you are true heroes!” he added.
