Speaking in Washington, D.C., ahead of the 75th annual NATO Summit on Tuesday, Ukrainian President Volodymyr Zelenskyy expressed pain regarding Russia’s Monday attacks in Ukraine that killed at least 44 people in five cities and damaged a key children's’ hospital in Kyiv. “It's so difficult to lose children. And, of course, you see these people, you see parents, and when their children are dying or dead… you want to kill Putin. All of us, we want it very much,” Zelenskyy said.
