In an unscheduled TV address, the Russian leader said the Oreshnik missile could not be intercepted and promised to carry out more tests, including in “combat conditions”.
Russia’s use of the Oreshnik capped a week of escalation in the war that also saw Ukraine fire US and British missiles into Russia for the first time.
Ukrainian President Volodymyr Zelensky called for world leaders to give a “serious response” so that Putin “feels the real consequences of his actions”.
His country was asking Western partners for updated air defence systems, he added.
According to news agency Interfax-Ukraine, Kyiv is seeking to obtain the US Terminal High Altitude Area Defense (THAAD), or to upgrade its Patriot anti-ballistic missile defence systems.
