The Kremlin says that changes in Russia’s nuclear doctrine are intended to discourage Ukraine’s Western allies from supporting attacks on Russia

The Kremlin said on Sunday that amendments to Russia's nuclear doctrine had been prepared and were about to be formalised, meaning the relevant documents setting out the circumstances in which nuclear arms can be used by Moscow will be updated.

Kremlin spokesman Dmitri Peskov said on Sunday that Moscow's revised nuclear weapons doctrine is needed because NATO infrastructure is approaching Russia's borders ever more closely. Peskov told Russian state television that Western powers are seeking victory over Russia through their arms deliveries to Ukraine.

In Kyiv, multiple explosions and machine gun fire could be heard throughout the night as the Ukrainian capital’s air defenses fought off a drone attack for five hours. No casualties were reported in Kyiv or elsewhere,

Russian forces have now launched the highest number of drone strikes in a single month since the conflict began in February 2022
