Kyiv is heavily protected by air defences, but Putin says the Oreshnik, which Russia fired for the first time at a Ukrainian city last week, is incapable of being intercepted - a claim greeted with scepticism by Western experts.

The Russian leader says the Oreshnik ballistic missile could be used to strike ‘decision-making centres’ in the Ukrainian capital.

President Vladimir Putin has threatened to target Kyiv's "decision-making centres" with a new ballistic missile. Questions have been raised about its potential impact and speed after it was used to attack the Ukrainian city of Dnipro last week.
