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.

The Kremlin fired a new intermediate-range ballistic missile at Ukraine on Thursday in response to Kyiv's use this week of American and British missiles capable of striking deeper into Russia, President Vladimir Putin said.

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.
