Russia has not provided "plausible evidence" to support its claim that Kyiv launched a large-scale drone attack on one of President Vladimir Putin's residences, Ukraine's foreign minister said Tuesday. “Almost a day has passed and Russia still has not provided plausible evidence for its accusations about the alleged 'Ukrainian attack on Putin's residence.' And they won't. Because there isn't any. No such attack took place,” Andrii Sibiga asserted on the social network X. He also lamented the condemnations of the alleged attack by the United Arab Emirates, India, and Pakistan. “Reactions like these to Russia's manipulative and unfounded claims only serve Russian propaganda and encourage Moscow to commit more atrocities and lies,” he added, and considered that they “undermine the constructive peace process that is currently underway.” The Kremlin will “toughen” its negotiating stance. Russia accused Ukraine on Monday of attacking an official Putin residence in the Novgorod region, between Moscow and St. Petersburg, with 91 drones in the early hours of the morning. Later, the Kremlin reported a telephone conversation between Putin and his US counterpart, Donald Trump, in which the Russian leader informed Trump of what had happened and indicated that the attack by Kyiv would not go unanswered. The Kremlin asserted today that its stance in the negotiations on the conflict in Ukraine would "harden" as a consequence of the alleged attack, while refusing to provide evidence, as Ukraine has requested, because all the drones "were shot down." "I don't think there should be evidence if such a massive drone attack is carried out and, thanks to the well-coordinated work of the air defense system, they were shot down," declared Kremlin spokesman Dmitry Peskov, adding that in any case, the Ministry of Defense should be asked if there are any possible wreckage. When asked how the Russian stance would harden, Peskov replied that, like the previous negotiating position, this "will not be made public."
