Russia has intensified its offensive in northeastern Ukraine to break through its heavily fortified defence and recapture the Kupiansk-Lyman area. The Russian Army is preparing for “serious offensive actions” and sending more staff in Kupiansk-Lyman, commander of the Ukrainian ground forces Oleksandr Syrskyi said. The fighting had "significantly escalated", he said, adding, "The main goal is to break through our troops’ defences and recapture our territory". But Ukraine’s eastern forces said president Volodymyr Zelensky’s forces were putting up a tough fight from well-entrenched troops, forcing Russian soldiers to retreat. “Our fortifications there are quite reliable. We have a powerful, dug-in position,” Ilia Yevlash, spokesperson for Ukraine’s forces in the east, told Ukrainian television. “So the enemy got it right in the teeth and retreated in order to regroup.” Russia captured the northeastern towns near Ukraine’s second-largest city of Kharkiv when the invasion began but Ukrainian forces recaptured the areas last year, evicting invading forces from some parts of the country’s Donbas industrial heartland. Its recapturing marked a significant step in the Ukrainian offensive to defend its territories. The Russian defence ministry acknowledged that it launched an “intense military activity” in the area and repelled 10 Ukrainian attacks in the Kupiansk area and two more in adjacent Lyman. In June, Ukraine initiated a counteroffensive with the primary objective of reclaiming territory in the eastern region, notably in the vicinity of Bakhmut, which had fallen under Russian control in May. Their strategy also involved advancing southward toward the Sea of Azov. The Ukrainian military primarily achieved gradual progress, disregarding criticism from certain Western observers who contended that the offensive was proceeding too slowly. Over the past week, the focus on the eastern front has shifted from Bakhmut to Avdiivka, a town located further southwest renowned for its substantial coking plant. The leading local authority in Avdiivka said there was a temporary calm in the city but they anticipated a forthcoming assault. “Shelling has diminished, there was less today,” Vitaliy Barabash, head of Avdiivka’s military administration, told national television, while noting that two people were killed in a nearby village. “We expect there will be new waves of heavy attacks in the days to come.” Read More Ukraine-Russia war – live: Putin suffers serious losses in largest offensive in months Sushi standoff spreads as Russia joins China in banning Japanese seafood Russian governor reported to police for speaking out over Putin’s ‘unnecessary’ war against Ukraine The Body in the Woods | An Independent TV Original Documentary The harrowing discovery at centre of The Independent’s new documentary
