Recent Ukrainian attacks in the Black Sea have compelled the Russian navy to rebase its ships, according to the Ukrainian navy. Dmytro Pletenchuk, a Ukrainian navy spokesman, confirmed that no Russian naval vessels remain in the Sea of Azov. Russian ballistic missile strikes on Kharkiv on Wednesday damaged the office of a Swiss mine-clearing NGO, injuring six people. Kharkiv mayor Ihor Terekhov reported that an industrial area was targeted. Kharkiv police head Volodymyr Tymoshko described a "double-tap" attack aimed at rescuers, who fortunately evacuated just before the second strike. Heavy Russian attacks have intensified around Pokrovsk in the Donetsk region, making conditions "tense" and difficult. Ukrainian forces continue to defend the area. The Institute for the Study of War (ISW) noted marginal Russian advances near Kharkiv and confirmed progress in Donetsk oblast. The ISW highlighted Russia's significant challenges in maintaining troop numbers and replacing heavy losses of equipment. Ukrainian authorities noted that Russia's current production is insufficient to cover these losses, with a British assessment indicating that Russia can only sustain operations until 2026-2027 by refurbishing Soviet-era stocks.
