Nato and Kyiv will hold emergency talks on Tuesday over Russia’s use of an experimental, hypersonic ballistic missile.

The Kremlin fired the new intermediate-range ballistic missile at a central Ukrainian city on Thursday in response to Kyiv’s use of American and British missiles capable of striking deeper into Russia.

In a televised address, Vladimir Putin, the Russian president, said that US air defence systems would be powerless to stop the new missile, which he said flies at ten times the speed of sound and which he called the Oreshnik, meaning hazelnut.
