Russia has been firing ballistic missiles at Ukraine, including a deadly strike on the Kyiv region on Wednesday. Attacks like the one on Wednesday, he said, “will continue as long as the enemy has ballistic missiles.” Russia, since the start of the war, has fired “scores” of North Korean ballistic missiles at Ukraine, but it appears more are to come. “Ballistic missile defence is one of Ukraine’s greatest vulnerabilities, so any increase in the quantities of ballistic missiles they face will pose a greater challenge,” Rob Lee, a senior fellow at the Foreign Policy Research Institute, told Reuters. The Kyiv Independent reported that North Korea’s ballistic missiles, much like Russia’s, can only be intercepted by the Patriot missile system.
