Ukrainian forces advance near Kupiansk as Russia claims progress around Sumy

Ukrainian troops continue to press forward along the right bank of the Oskil River north of Kupiansk, with Ukrainian authorities expected to announce control over roughly 200 square kilometers in the Lyman sector.

Meanwhile, the Russian Ministry of Defence reported capturing several frontline settlements approaching Sumy. Russian forces also launched targeted strikes against military infrastructure in the Kyiv region, damaging ammunition storage facilities.

On the southern front, Valery Gerasimov, Chief of the Russian General Staff, personally refuted claims of Ukrainian advances in the Zaporizhzhia region, maintaining that Russian defensive lines remain secure despite ongoing clashes across eastern and northern Ukraine.
