Russian forces have attacked Ukraine’s capital, Kyiv, with a wave of ballistic missiles, officials said. Kyiv Mayor Vitali Klitschko said a 20-storey residential building in the city’s Obolon district is on fire following the Russian attack. In a post on Telegram, Klitschko also said that air defence units were in action to repel the assault. Ukraine has in recent months urged its allies for more supplies of US-made Patriot missile interceptors to protect its airspace against Russian ballistic attacks. Ukrainian President Volodymyr Zelenskyy has said a lack of ballistic missile interceptors “only encourages Russia to launch such attacks that take human lives”.
