The Pentagon says the Oreshnik is a tweak of Russia’s RS-26 Rubezh missile, an intercontinental ballistic missile (ICBM) that has been tested since 2011.

Russian President Vladimir Putin said in a televised address that the attack was a test of Russia's "newest missile," an IRBM called "Oreshnik."

Vladimir Putin has claimed Moscow launched a new hypersonic ballistic missile against Ukraine in response to strikes by Kyiv inside Russia using UK and US long-range missiles.

This is the first time Russia has used its so-called Oreshnik intermediate-range ballistic missile in combat. The launch also serves as a warning to the West.

NATO members on Tuesday reaffirmed their support for Ukraine during talks with the country's officials held in response to Russia's launch of an experimental intermediate-range ballistic missile last week.

The meeting also included the acting commander of the Air Force of the Armed Forces of Ukraine, Lieutenant General Anatoliy Kryvonozhko.
