Drone Strikes Hit Kyiv Science Academy and Kharkiv High-Rise, Injuring 43 as Russia Vows Revenge

A pre-dawn strike hit a high-rise building in Kharkiv, Ukraine's second-largest city, injuring 43 people [253083]. Later, during working hours, drone attacks struck a business center in central Kyiv and a national science institution in Dnipro, killing four people [253083].

In Kyiv, a Russian drone hit the historic building of Ukraine's National Academy of Sciences [252812]. The building was badly damaged during large Russian drone attacks on the capital on Monday, and people clung to the windows to escape [252749]. The academy is an institution credited with over 90 percent of the country's scientific discoveries, including advances in astronomy and military technology [253031].

Kremlin spokesman Dmitry Peskov said Ukraine must "pay a price" after a jet-powered drone hit Kyiv's Academy of Sciences, calling Russia's intensified strikes part of that price [253078].

Separately, a Ukrainian Hornet drone struck a Russian radar station 120 kilometers behind the front line, likely destroying a Nebo-M system worth approximately $100 million [253080]. The Nebo-M is a mobile radar system designed to detect and track aircraft, missiles, and drones at long range, and Russia uses it to coordinate air defenses and guide strikes against Ukrainian targets [253080]. A brigade officer said the strike is part of a broader Ukrainian effort to cut Russian logistics and deprive Russian forces of radar and electronic warfare capabilities [253080].
