Russian forces launched a massive attack on the territory of Ukraine on the night of Sunday, May 24. Most reports of strikes came from Kyiv and the surrounding area. In the Ukrainian capital, according to the latest data provided by the city's mayor Vitali Klitschko, two people were killed. Another 44 people were injured, 28 of whom, including two children, were hospitalized. Earlier, Klitschko reported that drones hit multi-story residential buildings in the Shevchenkivskyi district in the central part of the capital. Additionally, in the Obolon district in northern Kyiv, a drone struck a 16-story residential building at the 12th-13th floors, while in the Solomianskyi district in the western part of the city, it hit a 24-story residential building at the 20th floor. Social media users published videos of the fire, presumably filmed in the Solomianskyi district. Moreover, debris from drones and missiles was recorded falling in various districts of Kyiv and its suburbs, leading to fires, Klitschko reported. **Media: Russia Strikes Kyiv and Bila Tserkva with 'Oreshnik'** The online publication Times of Ukraine and several monitoring Telegram channels, relying on videos from social media, suggest that the Russian Federation struck an unspecified target in the city of Bila Tserkva south of Kyiv with a medium-range ballistic missile 'Oreshnik'. At the time of publication, official sources from Ukraine and Russia had not confirmed the use of the missile. However, social media users published videos from multiple angles showing the characteristic separation of the missile's warhead and powerful explosions typical of the 'Oreshnik'. **Use of 'Oreshnik' in the War of the Russian Federation Against Ukraine** If the strike with the 'Oreshnik' missile is confirmed, it will be the third recorded instance of this ballistic missile being used by Russian forces since the beginning of the full-scale invasion of Ukraine. Previously, Russia attacked Ukraine with the 'Oreshnik' in November 2024. Russian President Vladimir Putin stated that the strike targeted the military-industrial complex in Dnipro and that Russia has a stock of such missiles ready for use, with their serial production already organized for the purpose of 'testing' the missile. In January 2026, Russia again attacked Ukraine with the 'Oreshnik', targeting a facility in the Lviv region in the west of the country. The Russian Ministry of Defense then claimed that the strike disabled the Lviv Aircraft Repair Plant. The latest use of the ballistic missile was justified by Russian authorities as a response to an alleged attempt by Ukrainian drones to attack Putin's residence in Valdai at the end of 2025. Even U.S. President Donald Trump reacted skeptically to Russia's claims of the alleged attack, to whom Moscow allegedly provided evidence of the incident. Ukrainian President Volodymyr Zelensky warned on May 23 about Russia's preparations for another use of the 'Oreshnik', citing intelligence data. He urged Kyiv's partners to respond to such actions by Russia and its prolongation of the war 'not post factum, but preventively' by increasing pressure on Moscow, according to 'Deutsche Welle'.
