In a dramatic escalation, Russian President Vladimir Putin has issued his second warning to the U.S. and NATO in just 24 hours, announcing the readiness of Russia’s powerful Oreshnik hypersonic missile system.

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.

The Kremlin has been clear that it views the supply of Western weapons to Ukraine as a hostile act, with Putin warning of a potential retaliation.
