Volodymyr Zelenskiy acknowledged that Ukrainian forces would be unable to regain control over Crimea and said the US won’t have to commit troops as part of security guarantees in an apparent overture to President Donald Trump.

US President Donald Trump has said he is "not happy" with deadly Russian strikes on Kyiv and that President Vladimir Putin should "stop" - but has not said if further action might be taken against Russia. Overnight into Thursday, the attacks on the Ukrainian capital killed at least 12 people and injured 90 others.
