MOSCOW Russian President Vladimir Putin on Friday promised more combat test-firing of an experimental hypersonic missile launched at Ukraine , as Volodymyr Zelensky appealed for updated air-defense systems to meet the new threat. The latest statements from the leaders came hours after Ukraine's parliament shut down over heightened fears of a missile attack. A day after Moscow fired the new missile at the Ukrainian city of Dnipro, Putin said there would be more tests of the new Oreshnik missile.
