President Vladimir Putin said on Friday that Russia would keep testing its new Oreshnik hypersonic missile in combat and had a stock ready for use, while Ukraine said it was already at work to develop air systems to counter the weapon.

It comes after Russian foreign ministry says a United States anti-missile base in Poland is now ‘a priority target’

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.
