Russia will harden its stance in peace negotiations with Ukraine after alleging that Kyiv launched a long-range drone attack targeting President Vladimir Putin’s residence, the Kremlin said. Spokesperson Dmitry Peskov claimed the incident was aimed at undermining U.S. President Donald Trump’s efforts to broker peace. Ukraine has strongly denied the accusation, with President Volodymyr Zelenskyy calling it a fabrication meant to manipulate talks. Moscow says 91 drones were involved, though it has not presented evidence. The claims have further escalated tensions amid fragile diplomatic efforts to end the war.
