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.

Russian President Vladimir Putin says Moscow has tested a new intermediate-range missile in a strike on Ukraine and that it could use the weapon against countries that have allowed Kyiv to use their missiles to strike Russia.
