Zelenskyy said Russian forces used ballistic missiles supplied by North Korea in their overnight attack on the southeastern Ukrainian city of Zaporizhzhia, where local officials said six people were killed and 19 wounded. A further three people, including a 15-year-old boy, were killed by Russian drones and artillery in the central Dnipropetrovsk region, local authorities said. Russia has received additional ballistic missiles from Pyongyang and is preparing to deploy more North Korean troops, Zelenskyy said late Monday. Russian President Vladimir Putin and North Korean leader Kim Jong Un signed a strategic partnership agreement just over two years ago. Meanwhile, the Russian Defence Ministry said its air defences overnight intercepted almost 400 Ukrainian drones over 14 Russian regions and occupied Crimea.
