Moscow has formally warned of "unpredictable consequences" if the US and allies keep supplying weapons to Ukraine.

But Ukraine's President Zelensky said "you can make the war shorter" if the world keeps supplying weapons to the country. He warned of the possibility of Russia targeting Ukraine with a nuclear strike.

Overnight new strikes hit the outskirts of the Ukrainian capital, Kyiv, and explosions were heard in the western city of Lviv.

Russia has today banned UK PM Boris Johnson and other senior ministers from entering Russia over the country's "hostile" stance on the war.
