Kyiv says Moscow used North Korean missilesSeven workers were killed at a Ukrainian steel plant on Tuesday during a Russian attack on the southeastern city of Zaporizhzhia in which President Volodymyr Zelenskiy said Moscow used North Korean ballistic missiles. The Zaporizhstal plant was forced to suspend production after being hit as Russia pummelled Zaporizhzhia with Zircon hypersonic missiles, guided aerial bombs and ballistic missiles supplied by Pyongyang. Regional governor Ivan Fedorov posted photos of buildings and vehicles ablaze after the strike, which also damaged four residential buildings. Russia's defence ministry said Russian forces had struck a metallurgical plant in Zaporizhzhia that produces flat-rolled steel which it said was used by the Ukrainian military. The attacks followed a Ukrainian drone strike that Russian authorities said on Monday had killed at least 13 people and wounded 39 in Nizhnekamsk, one of the heaviest civilian tolls in Russia in months.
