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 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.

Putin seems to be winning. Russian forces are pushing ahead in Ukraine. President-elect Donald J. Trump is returning to the White House. War fatigue is spreading across Europe. North Korean troops have boosted the ranks of his army.
