Ukrainian military radio technology expert Serhii "Flash" Beskrestnov says Russia struck Kyiv's historic center overnight with an Iskander ballistic missile carrying a K5 cluster warhead. According to him, the warhead contains 58 submunitions that detonate in the air and are intended to maximize effects on people and equipment across a 400 by 400 meter area. Flash said the strike was not aimed at a military target and reported many wounded civilians and destruction. #Ukraine
