KYIV, Nov 22 (Reuters) - The Russian missile that struck the Ukrainian city of Dnipro on Thursday reached a top speed of more than 13,000 kph (8,000 mph) and took about 15 minutes to reach its target from its launch, Ukraine said on Friday in its first public assessment of the new weapon.

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

Russia’s use of a new nuclear-capable hypersonic ballistic missile in Ukraine is not only escalating the war but lobbing an unmistakable threat at Europe and the West.
