President Vladimir Putin said Friday that Russia will continue to test and start mass-producing the hypersonic ballistic missile that it fired at Ukraine Thursday.

Russian President Vladimir Putin said his forces may use a new missile again after targeting Ukraine in retaliation for Kyiv’s use of American and British-made weapons on Russian territory this week.

The new ballistic missile fired by Russia struck a military-industrial facility in the central Ukrainian city of Dnipro, but its real mission was delivering a deadly new message to NATO.
