Russian invasion of Ukraine: What you need to know about what is happening today

Graphic saying Ukraine: What you need to know today

Keep up to date with what is happening in Ukraine with our daily wrap-up of headlines. 

US President Joe Biden has warned Russia that Nato will retaliate if chemicals are used in the war in Ukraine.

President Biden and western allies have pledged new sanctions and humanitarian aid in response to Vladimir Putin’s assault on Ukraine, but their offers fell short of Ukrainian President Volodymyr Zelensky’s pleas.

Mr Biden also announced the US would welcome up to 100,000 Ukrainian refugees — though he said many probably prefer to stay closer to home — and provide an additional 1 billion dollars (£760 million) in food, medicine, water and other supplies.

Boris Johnson has said Ukraine will ‘certainly win’ against Russia

Ukraine can “certainly win” against Russia, Boris Johnson has said, as western allies strengthened their position against the Kremlin by pledging there would be a “very severe response” to any chemical attack launched by Moscow.

Mr Johnson said “the situation for the Ukrainians is grim, miserable”, but he praised “Churchillian” leader Volodymyr Zelensky and said: “I think Ukraine can certainly win.”
