Spotlight: Russian forces launch a record number of drones at Ukraine
Between the evening of 23 May and early on 26 May, Russia launched the largest wave of drone strikes in Ukraine since the beginning of the invasion in early 2022. According to Ukrainian authorities, Russian forces launched over 900 Shahed-type attack and decoy drones,1Yuriy Svyrydyuk, “‘Iskanders’ and ‘Shaheds’: the Air Force told about the massive attack of the Russian Federation,” Suspilne, 24 May 2025 (Ukrainian); Roman Petrenko, “Russia launches nearly 300 drones and 70 missiles overnight, with hits recorded at 22 locations,” Ukrainska Pravda, 25 May 2025; Valentyna Romanenko, “Another record drone attack by Russia: Ukrainian air defence neutralised 288 UAVs and destroyed 9 cruise missiles,” Ukrainska Pravda, 26 May 2025 damaging civilian infrastructure and killing and injuring civilians across 16 regions, including the western regions of Chernivtsi, Ivano-Frankivsk, and Khmelnytskyi.
